  • regular expressions for class name

    - by user576701
    i need a regular expressions string to get all anchor tags in a page with a specific css class name, in c#/vb.net this is what i got so far "<a.*?href=""(.*?)"".*?>(.*?)</a>" but my attempts to add "class=name" isnt working, also is it possible to find links where the class name appears either before or after the href with one expression ? i am familiar with 3rd party html libraries, but thats an overkill for what i have in mind, so is the webbrowser control.

  • 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.

  • 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.

  • 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.

  • Finding C#-style unescaped strings using regular expressions

    - by possan
    I'm trying to write a regular expression that finds C#-style unescaped strings, such as string x = @"hello world"; The problem I'm having is how to write a rule that handles double quotes within the string correctly, like in this example string x = @"before quote ""junk"" after quote"; This should be an easy one, right?

  • 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.

  • "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.

  • 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. I was wondering if anyone else knows a way to reference the publishers URL preferably by their publisher ID or some other way?

  • 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.

  • 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; }

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!

    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.
