Hi guys im interested in extracting 11075 and e9.bogeyman, from the line below.

Code:
<td><a href="?section=profile&amp;show=sig&amp;id=11075">e9.bogeyman</a> <img src="gfx/laenderflaggen/Singapore.gif" alt="[SG]" title="Singapore"> <img src="gfx/laenderflaggen/Denmark.gif" alt="[DK]" title="Denmark"></td>'


The length of the name and numbers may differ. Also there might be a diffrence in the actual line number (in this case its 220)

My own best suggestion would be to download the file, use a loop to search each line for the string :

href="?section=profile&amp;show=sig&amp;id

however this method might be slow, and the script needs to parse around 100.000 html documents. Also I dont know how to point out the number and name (as these may vary in size)

Any suggestions ?

thx in advance

Loop, Read + something like InStr() or FileRead + RegExMatch or xpath.

The name and number will differ each time, so what to search for ?

I could use RegExMatch but I would need clumpsy loops too ?

if I try to search for "http://thisiswhatcomesbeforethenumber?" and lets say I get position called 7.

I would have 7, then i can go to endpos of the string, but i still dont know how long the number or name is. the length could be between 1 and 10

So I would have to do a clumpsy loop, to look for a < sign ?

RegExMatch and Regular Expressions (RegEx) - Quick Reference and #EscapeChar (and explanation of escape sequences)

not-tested (and, there are RegEx cracks around that could probably shorten this considerably)

Code:
; the question-mark is escaped for regex
before := "<td><a href="\?section=profile&amp;show=sig&amp;id="
; the double-quote is escaped for ahk
between := """<"
after := "<"

; "(.*)" is regex for: return anything in match variable as array
pattern := before . "(.*)" . between . "(.*)" . after

FileRead, aFile, pathToAFile
RegExMatch(aFile, pattern, match)
MsgBox % match1 . " " . match2


HTH

There is a mistake in the script :wink:

To make it easier:

regex wrote:
the characters \.*?+[{|()^$ must be preceded by a backslash to be seen as literal


ahk wrote:
the characters ,%`'" might get special treatment, or have to be escaped (depends). Within an expression, two consecutive quotes enclosed inside a literal string resolve to a single literal quote.
