URGENT!: Seeking RegEx guru

April 25, 2007 ·

No, not for a job, I just need to find a reg ex expression to find the values of the following expression: xpath("/root/framework_root/framework_mg/controllers/controller/message-listener/@message/text()", "|") basically its a function, you pass in two values, the xpath and then a delimiter. I need to get the value of the parameters. e.g. 1. /root/framework_root/framework_mg/controllers/controller/message-listener/@message/text()
2. | Any ideas? (I SUCK at RegEx, and I am hoping someone can show me the light!)

    xpath\("([^"]*)", "([^"]*)

    You don't say how the input could vary (is that space after the comma always there ? is it always lower case ?), so an alternative might be:
    \("([^"]*)",\s*"([^"]*)"

    What Tom said, except don't forget the close parenthesis:

    \("([^"]*)",\s*"([^"]*)"\)

    Also, what about single quotes? Maybe something like this?

    \((["'])([^'"]*)\1,\s*(['"])([^'"]*)\3"\)

    I didn't think the close ) was important.
    Also, we both forgot that people put spaces in funny places, which leaves us with:
    xpath\s*\(\s*"([^"]*)"\s*,\s*"([^"]*)"

    Mixing " and ' leads to problems (what it the first argument has a ' in but has " at both ends), something like ("|') might work better.

    In PHP:

    preg_match("/xpath\(\s*((?s:\"(?:(?!(?<!\\\)\").)+\"|'(?s:(?!(?<!\\\)').)+'))\s*,\s*((?s:\"(?s:(?!(?<!\\\)\").)+\"|'(?s:(?!(?<!\\\)').)+'))\s*\)/",
    "xpath('blabla\'blabla\'bllaal', \"foo\")",
    $m);
    print_r($m);

    /**
    Array
    (
    [0] => xpath('blabla\'blabla\'bllaal', "foo")
    [1] => 'blabla\'blabla\'bllaal'
    [2] => "foo"
    )
    */
