[SOLVED] Silly regex...

[marklarah]

Hi!

 

So I'm scraping a page, and the following text comes up, from which a string needs extracting/

        <a class="nav"

  title="|Bar 24"

  href="index.php?page=session=g7657h7h575&token=[NEEDTHISSTRING]">

 

The session=g7657h7h575, I already will have the session key stored in a variable, (but not the 24, the number could be a one or two digit number.)

 

Anyway, I've been pulling my hair out with preg_matches and m tokens and (.+?) and stuff...nothing seems to work. Anyone want to guide me in the right direction? Thanks....

Ie, can anyone help me set up a regex string to find the token? I assume this would be quite simple. Thanks.

Assuming the string is always in that exact form you could use something along the lines of...

 

'#token=([^"]+)#'

 

I'd imagine the token would have a specific length as it is likely a hash? If thats the case then you could make a slightly more specific pattern. Hopefully that makes sense I have had a pint or six .

[marklarah]

Aye...it's 32 characters long everytime, so it is a hash, you're quite correct.

 

However, what you gave me works perfectly! I love you!

 

Thanks...I didn't really think about ignoring the rest of the string...

Glad it's working, as it's a hash you could probably make it a bit more accurate using something like...

 

'#token=([a-z1-9]{32})#'

 

That way your not reliant on the token being the last parameter in the URL.
