    regular expression for matching XML

    hmmm, there isn't a "general" forum for questions so i figure i'll post here.

    i'm monitoring traffic with winpcap and i want to parse out all XML messages. when the data comes in i filter everything out so that only ASCII characters are parsed, so that takes care of all the extra crap.

    here's the regex string i'm using

    Code:
    <(-[A-Za-z0-9:]+)[- &/:;'\.="]*>.*</\1>
    it seems to work, but there might be some cases i'm missing. any ideas? thanks.

    You are right, there are two.

    And this question has been asked several times, so be a good sport and utilize the search function.

    i searched the i only found 1 match:
    xml file parsing in C

    however, that doesn't match a SOAP envelope header...actually what i posted doesn't either...

    Drats... I remember one that had links to some pretty nice reg-ex libraries.

    ooops, i found the error (the 2nd part only takes special characters but not regular alphanumerics, the following appears to be working:

    Code:
    <([-:\w]+)[-:=\s"/\.\w]*>.*</\1>
