  • How do I select all parenting items based on a given node's attribute in php's xPath?

    - by bakkelun
    I have an XML feed that looks something like this (excerpt): <channel> <title>Channel Name</title> <link>Link to the channel</link> <item> <title>Heading 1</title> <link>http://www.somelink.com?id=100</link> <description><![CDATA[ Text here ]]></description> <publishDate>Fri, 03 Apr 2009 10:00:00</publishDate> <guid>http://www.somelink.com/read-story-100</guid> <category domain="http://www.somelink.com/?category=4">Category 1</category> </item> <item> <title>Heading 2</title> <link>http://www.somelink.com?id=110</link> <description><![CDATA[ Text here ]]></description> <publishDate>Fri, 03 Apr 2009 11:00:00</publishDate> <guid>http://www.somelink.com/read-story-110</guid> <category domain="http://www.somelink.com/?category=4">Category 1</category> </item> <channel> That's the rough of it. I'm using this piece of PHP (excerpt): $xml = simple_xml_load_file($xmlFile); $xml->xpath($pattern); Now I want to get all ITEM-nodes (with their children) based on that pesky "domain" attribute in the category node, but no matter what I try it does-not-work. The closest I got was "//category[@domain= 'http://www.somelink.com/?category=4']" The expression I tried gave me this result: [0] => SimpleXMLElement Object ( [@attributes] => Array ( [domain] => http://www.somelink.com/?category=4 ) [0] => Category 1 [1] => SimpleXMLElement Object ( [@attributes] => Array ( [domain] => http://www.somelink.com/?category=4 ) [0] => Category 1 The expression should contain all childrens of the two items in the example, but as you can see only the info in the category node is present, I want all the item nodes. Any help would be highly appreciated.

  • Why is T() = T() allowed in C++?

    - by Rimo
    I believe the expression T() creates an rvalue (by the Standard) However the following code compiles (at least on gcc4.0) class T {... }; int main() { T() = T(); } I know technically this is possible because member functions can be invoked on temporaries and the above is just invoking the operator= on the r-value temporary created from T(). But conceptually this is like assigning a new value to an r-value. Is there a good reason why this is allowed?

  • Using eachDirMatch to skip .svn folders

    - by algernon
    I'm writing a program which needs to traverse a set of directories. Tried to use the following code: file.eachDirMatch(/.*[^.svn]/){ //some code here } But that ended up match none of my directories. I realize this boils down figuring out the right regex hang head in shame but even after revisiting some Java Regular Expression documentation I thought this should work.

  • python copytree with negated ignore pattern

    - by Chris H
    I'm trying to use python to copy a tree of files/directories. is it possible to use copytree to copy everything that ends in foo? There is an ignore_patterns patterns function, can I give it a negated regular expression? Are they supported in python? eg. copytree(src, dest, False, ignore_pattern('!*.foo')) Where ! means NOT anything that ends in foo. thanks.

  • why jquery can't be used in my $(document).ready() function?

    - by Firegun
    The page can be viewed at http://cistrome.org/cps/seqconfig?did=2693 When load in Firebugs, it gives me this error: TypeError: $(".open_gene").on is not a function [Break On This Error] $(".open_gene").on('change', function(event) { However, if I type in this expression in Firebug's console, it can be evaluated as a function without any problems: >>> $(".open_gene").on function() I was wondering what might be the reason to cause this issue. Does anyone have ideas about this? Thanks!

  • How to match !x but not !!x in JS regex?

    - by mpeterson
    Given the following text: This is!!xa simple string!xpattern I would like to get a regexp that matches the !x that's between "string" and "pattern" but not !!xa that's between "is" and "a". This regexp is to be used inside a string split(). I have tried several combinations but I cannot get a regexp that meets my needs. Perhaps my expression is not so regular after all =) Thanks in advance!

  • LINQ display row numbers

    - by timvaines
    I simply want to include a row number against the returned results of my query. I found the following post that describes what I am trying to achieve but gives me an exception http://vaultofthoughts.net/LINQRowNumberColumn.aspx "An expression tree may not contain an assignment operator" In MS SQL I would just use the ROWNUMBER() function, I'm simply looking for the equivalent in LINQ.

  • C++ Question on the pow function.

    - by Sagistic
    I'm trying to get this expression to work, I'm pretty sure its not the parenthesis because I counted all of them. Perhaps there something I'm doing wrong involving the parameter pow (x,y). double calculatePeriodicPayment() { periodicPaymentcalc = (loan * ((interestRate / yearlyPayment))) / (1-((pow ((1+(interestRate / yearlyPayment)))),(-(yearlyPayment * numOfYearLoan)))); return periodicPaymentcalc; }

    - by xarzu
    What are the limits of writing a C# app when you want a truly impressive GUI? At what point does one have to leave Visual C# behind and go into WPF? Also, if I choose to go with WPF, do I have to ditch the Visual Studio IDE and go with Expression Studio?
