• How to match a variable list of items separated by commas

  - by user261915

  I want to turn something like this CS 240, CS 246, ECE 222, ... (more or less); Software Engineering students only into ('CS 240', 'CS 246', 'ECE 222', 'ECE 220') in Python, code that matches a single course looks like >>> re.search('([A-Z]{2,5} \d{3})', 'SE 112').groups() ('SE 112',) I prefer a regular expression only method because I have a bunch of other alternate reg exps using '|' to combine them. However, a method with split is acceptable.

• 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.

• "Slice" out one element from a python dictionary

  - by BCS

  I have a dictionary: D = { "foo" : "bar", "baz" : "bip" } and I want to create new dictionary that has a copy of one of it's elements k. So if k = "baz": R = { "baz" : "bip" } what I'v got now is: R = { k : D[k] } But in my case k is a complex expression and I've got a whole stack of these. Caching k in a temporary looks about as ugly as the original option. What I'm looking for is a better (cleaner) way to do this.

• Why does this eval not work in Ruby

  - by Anil

  Can you explain this? I want to eval values and calculations from two different sources. One source gives me the following info(programmatically): 'a = 2' The second source gives me this expression to evaluate: 'a + 3' This works: a = 2 eval 'a + 3' This also works: eval 'a = 2; a + 3' But what I really need is this, and it doesn't work: eval 'a = 2' eval 'a + 3' I would like to understand the difference, and how can I make the last option work. Thanks for your help.

• Is there a way to look up the Publishers URL using the linkshare.com API

  - by steve

  I'm able to retrieve the URL of a publisher only if their URL is in the title or the description using regular expression in linkshare's coupon API but in doing so, that leaves me with a lot of publishers not having a reference to their website which I need for the type of site that I am building.
