StringRegExp

2 posts in this topic

Sorry if there is documentation on this function already but I could not seem to find it in the functions reference nor could I find a good google on it.

Basically I want someone to explain this:

StringRegExp($s_IE, "<A(.*?)>", 3)

$s_IE is the document.body.innerHTML of a website. I figured that the search expression

"<A(.*?)>" is saying locate everything with a <A> tag. My question is what does the 3 mean and what exactly is the syntax of .*?

Also, how would I go about extracting links that only start with this:

Start: <a href='profile.asp=

End: '>

The documentation for StringRegExp is in the beta help file installed with the beta version of AutoIt. The 3 in the third parameter tells StringRegExp to return an array with the text that match the pattern inside the parentheses, and find all occurances that match the pattern in the string. The pattern ".*?" is made of the atom ".", meaning match any character and a predicate of "*", which means match the preceding atom (any character) 0 or more times. The question mark tells StringRegExp to match the smallest string instead of the largest pattern (the default).

Please read the documentation included with the beta version of AutoIt and take a look at http://www.autoitscript.com/fileman/users/Nutster/ for my http://www.autoitscript.com/fileman/users/Nutster/RegExp%20Test%204.au3 for more patterns and what they can match.
