• Selecting a specific div from a extern webpage using CURL

  - by Paulo

  Hi can anyone help me how to select a specific div from the content of a webpage. Say i want to get the div with id="body" from webpage http://www.test.com/page3.php My current code looks something like this: (not working) //REG EXP. $s_searchFor = '@^/.dont know what to put here..@ui'; //CURL $ch = curl_init(); $timeout = 5; // set to zero for no timeout curl_setopt ($ch, CURLOPT_URL, 'http://www.test.com/page3.php'); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); if(!preg_match($s_searchFor, $ch)) { $file_contents = curl_exec($ch); } curl_close($ch); // display file echo $file_contents; So i'd like to know how i can use reg expressions to find a specific div and how to unset the rest of the webpage so that $file_content only contains the div.

• Create hyperlink in django template of object that has a space

  - by Ed

  I am trying to create a dynamic hyperlink that depends on a value passed from a function: {% for item in field_list %} <a href={% url index_view %}{{ item }}/> {{ item }} </a> <br> {% endfor %} The problem is that one of the items in field_list is "Hockey Player". The link for some reason is dropping everything after the space, so it creates the hyperlink on the entire "Hockey Player", but the address is http://126.0.0.1:8000/Hockey How can I get it to go to http://126.0.0.1:8000/Hockey Player/ instead?

• Using PHP session_id() to Make Sure iframe is Generated by Our Server Dynamically

  - by Michael Robinson

  We use iframes to show ads on our site. Iframes are used to allow us to keep the ad generation code and other site modules separate. As we track ad views on our site, and need to be able to keep an accurate count of which pagetype gets what views, I must ensure that users can't simply copy-paste the iframe in which the ad is loaded onto another site. This would cause ad count to become inflated for this page, and the count would not match the view count of the page the iframe "should" be displayed in. Before anyone says so: no I can't simply compare the page view count with the ad view count, or use the page view count * number of ads per page, as # of ads per page will not necessarily be static. I need to come up with a solution that will allow ads to be shown only for iframes that are generated dynamically and are shown on our pages. I am not familiar with PHP sessions, but from what little reading I have had time to do, the following seems to be to be an acceptable solution: Add "s = session_id()" to the src of the ad's iframe. In the code that receives and processes ad requests, only return (and count) and ad if s == session_id(). Please correct me if I'm wrong, but this would ensure: Ads would only be returned to iframes whose src was generated alongside the rest of the page's content, as is the case during normal use. We can return our logo to ad calls with an invalid session_id. So a simple example would be: One of our pages: <?php session_start(); ?> <div id="someElement"> <!-- EVERYONE LOVES ADS --> <iframe src="http//awesomesite.com/ad/can_has_ad.php?s=<?php echo session_id(); ?>></iframe> </div> ad/can_has_ad.php: <?php session_start(); ?> if($_GET['s'] == session_id()){ echo 'can has ad'; } else{ echo '<img src="http://awesomesite.com/images/canhaslogo.jpg"/>'; } And finally, copied code with static 's' parameter: <!-- HAHA LULZ I WILL SCREW WITH YOUR AD VIEW COUNTS LULZ HAHA --> <iframe src="http//awesomesite.com/ad/can_has_ad.php?s=77f2b5fcdab52f52607888746969b0ad></iframe> Which would give them an iframe showing our awesome site's logo, and not screw with our view counts. I made some basic test cases: two files, one that generates the iframe and echos it, and one that the iframe's src is pointed to, that checks the 's' parameter and shows an appropriate message depending on the result. I copied the iframe into a file and hosted it on a different server, and the correct message was displayed (cannot has ad). So, my question is: Would this work or am I being a PHP session noob, with the above test being a total fluke? Thanks for your time! Edit: I'm trying to solve this without touching the SQL server

• SimpleXML adding html into Hash tree

  - by Miriam Raphael Roberts

  Question: I have an xml file that I am pulling from the web and parsing. One of the items in the xml is a 'content' value that has HTML. I am using SimpleXML/XMLin to parse the file like so: $xml= eval { $data-XMLin($xmldata, forcearray = 1, suppressempty= +'') }; When I use Dumper to dump the hash, I dsicovered that SimpleXML is parsing the HTML into the hash tree. 'content' => { 'div' => [ { 'xmlns' => 'http://www.w3.org/1999/xhtml', 'p' => [ { 'a' => [ { 'href' => 'http://miamiherald.typepad.com/.a/6a00d83451b26169e20133ec6f4491970b-pi', 'style' => 'FLOAT: left', 'img' => [ etc..... This is not what I want. I want to just grab content inside of this entry. How do I do this?

• XMLHttpRequest cross site scripting on same server but differnt port

  - by clamp

  hello, using XMLHttpRequest it is not possible to open a connection to a document on a different domain than where the page itself is hosted. but what about different ports? for example i have a webserver running on my machine listening on port 80 so the webaddress would look like this: http://localhost:80/mypage.html and i have another webserver running on localhost which is meant to process the ajax requests but listens on a different port. so the javascript in mypage.html would look like this: var xmlhttprequest = new XMLHttpRequest(); xmlhttp.open("GET", "http://localhost:1234/?parameters", true); xmlhttp.send(); would this work? or will it give a security exception as well?

• UDP Tracker not responding

  - by kelton52

  Alright, so I'm trying to connect to UDP trackers using c#, but I never get a response. I also don't get any errors. Here's my code. namespace UDPTester { class MainClass { public static bool messageReceived = false; public static Random Random = new Random(); public static void LOG(string format, params object[] args) { Console.WriteLine (format,args); } public static void Main (string[] args) { LOG ("Creating Packet..."); byte[] packet; using(var stream = new MemoryStream()) { var bc = new MiscUtil.Conversion.BigEndianBitConverter(); using(var br = new MiscUtil.IO.EndianBinaryWriter(bc,stream)) { LOG ("Magic Num: {0}",(Int64)0x41727101980); br.Write (0x41727101980); br.Write((Int32)0); br.Write ((Int32)Random.Next()); packet = stream.ToArray(); LOG ("Packet Size: {0}",packet.Length); } } LOG ("Connecting to tracker..."); var client = new System.Net.Sockets.UdpClient("tracker.openbittorrent.com",80); UdpState s = new UdpState(); s.e = client.Client.RemoteEndPoint; s.u = client; StartReceiving(s); LOG ("Sending Packet..."); client.Send(packet,packet.Length); while(!messageReceived) { Thread.Sleep(1000); } LOG ("Ended"); } public static void StartReceiving(UdpState state) { state.u.BeginReceive(ReceiveCallback,state); } public static void ReceiveCallback(IAsyncResult ar) { UdpClient u = (UdpClient)((UdpState)(ar.AsyncState)).u; IPEndPoint e = (IPEndPoint)((UdpState)(ar.AsyncState)).e; Byte[] receiveBytes = u.EndReceive(ar, ref e); string receiveString = Encoding.ASCII.GetString(receiveBytes); LOG("Received: {0}", receiveString); messageReceived = true; StartReceiving((UdpState)ar.AsyncState); } } public class UdpState { public UdpClient u; public EndPoint e; } } I was using a normal BinaryWriter, but that didn't work, and I read somewhere that it wants it's data in BigEndian. This doesn't work for any of the UDP trackers I've found, any ideas why I'm not getting a response? Did they maybe change the protocol and not tell anyone? HTTP trackers all work fine. Trackers I've tried udp://tracker.publicbt.com:80 udp://tracker.ccc.de:80 udp://tracker.istole.it:80 Also, I'm not interested in using MonoTorrent(and when I was using it, the UDP didn't work anyways).

• Email form isn't sending

  - by Jonathan

  Hi I have an email form that isn't sending out an email to the recipient or a copy to the client. The form can be found at www.kelcos.co.uk/contact and the files associated with this are: /index.php /jquery.js /sendemail.php /submitform.php /thanks.php /verify.php I have used this form on other websites http://www.bowlesgreen.co.uk/contact/ and http://www.arbortectreecare.co.uk/contact/ and it works fine - the only difference is that these other sites use my usual hosting provider and for the one that won't send I'm working through the clients hosting provider, which I can only presume is what is causing the problem. I have contacted the hosting and so far we have eliminated a few things such as: 'The limitation to our systems is that the emails sent using scripts will be blocked if they are not going to or coming from an email address setup on the web hosting account. - so I am now sending the form to an a kelcos.co.uk address, but still no joy. PHP/ASP was originally disabled, but now has been activated the mail() script is enabled I would really appreciated any advise any of you could offer. Thanks

• how to view internal jaxws logs in tomcat

  - by prmatta

  I have a web service that is deployed in tomcat, and it is rejecting a soap request over https. However, I can't see any logs as to why it is doing so. I have the following set in my service endpoint implementation file: System.setProperty("javax.net.debug", "all"); System.setProperty("java.security.debug", "all"); And I pass the following parameters to tomcat: -Dcom.sun.xml.ws.transport.http.HttpAdapter.dump=true -Dcom.sun.xml.ws.transport.http.client.HttpTransportPipe.dump=true Is there anything else I need to do to see the internal jaxws logs? Are there some other loggers I need to enable?

• Win32 Window Menu is appearing along left side instead of across top of window

  - by Khat

  I think I may be using a wrong window style or something or maybe just adding the menu to the window incorrectly. I'll post a link to an image here so you can see what I mean about the menu not diplaying correctly: http://img707.imageshack.us/img707/4828/wtfmenu.jpg And here's a link to the code that creates the menu and the window: http://pastebin.com/CBrSVXUD I'm sure I'm missing something simple and dumb in the labyrinth of styles, settings and etc that are part and parcel for the Win32 API. Has anyone seen this before and know what I'm doing wrong? I just want a 'normal' menu bar along the top, snug against the title bar. Thanks in advance for any advice.

• PHP regular expression

  - by Ferol

  such text: $text = ' href="http://yahoo.com" target="_blank"> link text </a> text... text... <br> text...'; // $text = ' text... <a href="http://yahoo.com" target="_blank"> link text </a> text... text... <br> text...'; and such regular expression: preg_match_all('/^(.*)(<.+>)(.*)(<\/.+>)(.*)$/',$text,$matches); what I want, - to check if text matches the regular expression. If yes, then $matches should contain parts of string above, if not (as I guess) it should contain four zero-length arrays. something is wrong, but I can't find, what actually is?

• How to add SSL to subdomain that points to a different server?

  - by Travis

  I don't know much about secure certificates, so please bear with me... I've got a webserver that has a single domain SSL certificate https://secure.mysite.com I also have a couple of subdomains that point to different servers. http://www.mysite.com ( main server) http://subdomain.mysite.com (completely different server) I am wondering: What is the best way to add SSL to the subdomain: https://subdomain.mysite.com Is it possible to configure something like this with a wildcard certificate? Or is it better to purchase another single-domain certificate and install it on the seperate server? Are there any special considerations / pitfalls in doing something like this? Thanks, in advance, for your help.

• Why does A* path finding sometimes go in straight lines and sometimes diagonals? (Java)

  - by Relequestual

  I'm in the process of developing a simple 2d grid based sim game, and have fully functional path finding. I used the answer found in my previous question as my basis for implementing A* path finding. (http://stackoverflow.com/questions/735523/pathfinding-2d-java-game). To show you really what I'm asking, I need to show you this video screen capture that I made. I was just testing to see how the person would move to a location and back again, and this was the result... http://www.screenjelly.com/watch/Bd7d7pObyFo Different choice of path depending on the direction, an unexpected result. Any ideas?

• Tomcat 6 configuration example for Ubuntu Linux?

  - by intargc

  I'm very new to Tomcat and I'm having some issues figuring out how to set it up. I set it up on Ubuntu Linux and started reading and trying to follow the information given on the apache website here: http://tomcat.apache.org/tomcat-6.0-doc/deployer-howto.html Apparently I'm missing something. I have a WAR named MyWebapp.war and it's in a directory /home/mywebapp. In /etc/tomcat6/Catalina/localhost/MyWebapp.xml, I have the following line: <Context path="/MyWebapp" docBase="/home/mywebapp" antiResourceLocking="false" /> Everything else is the default configuration that came with tomcat6 via the Ubuntu package. When I restart Tomcat and try to go to http://localhost:8080/MyWebapp, I get a 404. The WAR file isn't unpacked and nothing seems to be working. I'm going to be deploying two Grails applications on this server with Tomcat. Is there a more straight forward way to do this?

• Programmatically sync the db in Django

  - by Attila Oláh

  I'm trying to sync my db from a view, something like this: from django import http from django.core import management def syncdb(request): management.call_command('syncdb') return http.HttpResponse('Database synced.') The issue is, it will block the dev server by asking for user input from the terminal. How can I pass it the '--noinput' option to prevent asking me anything? I have other ways of marking users as super-user, so there's no need for the user input, but I really need to call syncdb (and flush) programmatically, without logging on to the server via ssh. Any help is appreciated.

Definitions that works in one domain class does not when applied to another (with different names of course). http://www.grails.org/doc/1.1/guide/single.html#5.5.2.6%20Database%20Indices Some working examples and explanations would be highly appreciated!

• Cherokee rule failover

  - by phretor

  I have a Cherokee virtual host configured as follows: 1st rule: "Directory /" -> HTTP Reverse Proxy 2nd rule: "Directory /" -> uWSGI I know the second rule is useless because it's never triggered. However, the first rule seldom returns a 504 Gateway Timeout error so I was thinking of failing over the second rule, yet I don't know how to achieve this. Is it possible? Unfortunately, I cannot use only one rule with load balanced information sources, because I use two different types of information sources (i.e., pure HTTP and WSGI).

• Twitter Trends API weekly.json causing error "Cannot use object of type stdClass as array"

• Compressing as GZip WCF requests (SOAP and REST)

  - by Joannes Vermorel

  I have a .NET 3.5 web app hosted on Windows Azure that exposes several WCF endpoints (both SOAP and REST). The endpoints typically receive 100x more data than they serve (lot of data is upload, much fewer is downloaded). Hence, I am willing to take advantage from HTTP GZip compression but not from the server viewpoint, but rather from the client viewpoint, sending compressed requests (returning compressed responses would be fine, but won't bring much gain anyway). Here is the little C# snippet used on the client side to activate WCF: var binding = new BasicHttpBinding(); var address = new EndpointAddress(endPoint); _factory = new ChannelFactory<IMyApi>(binding, address); _channel = _factory.CreateChannel(); Any idea how to adjust the behavior so that compressed HTTP requests can be made?
