Hello, I'm back with a problem with regular expressions

I have this html code (is more extensive, but it is always the same, "and I need to list the text found between "> and </a> with regular expressions.

<img src="/icons/text.gif" alt="[TXT]" width="20" height="22"> <a href="2757817%202691586%20Installation%20instructions.htm"> 2,757,817 2,691,586 Installation instructions . htm </ a>
<img width="20" height="22"> <a src="/icons/text.gif" alt="[TXT]" 2732618_readme.htm href="2790817%202732618_readme.htm"> 2790817 </a>
<img width="20" height="22"> <a src="/icons/text.gif" alt="[TXT]" href="942146.reg"> 942146.reg </a>
<img src="/icons/text.gif" alt="[TXT]" width="20" height="22"> <a href="Windows6.1-KB2757817-x64%20Installation%20instructions.htm"> Windows6.1-KB2757817-x64 Installation instructions.htm </a>
<img src="/icons/text.gif" alt="[TXT]" width="20" height="22"> <a href="Windows6.1-KB976932-x64.html"> Windows6.1-KB976932-x64.html </a>

$sFilter = "msu|html|reg|txt"
$sString = '(?i)">([^< ].*?\.(?:' & $sFilter & '))</a>'

but there is an error, this is the result.

2757817 2691586 Installation instructions.htm

2790817 2732618_readme.htm

942146.reg

Windows6.html <== Error

Windows6.html <== Error

Can you help? THANKS!

PD: You can also take data from <a href=" and ">, but not how to replace the "%20" for spaces with ER.

_IEAttach
$oImgCol=_IEImgGetCollection OR _IELinkGetCollection

For $oImg In $oImgCol
consolewrite($oImg.href & " " & $oImg.href @crlf)
next

no need to do regexp on html

This is not the solution the OP wants, but I should not have deleted it. Sorry to anyone who was reading it. Reposting.

#include <array.au3>

Local $sTest = '<img src="/icons/text.gif" alt="[TXT]" width="20" height="22"> <a href="2757817%202691586%20Installation%20instructions.htm"> 2,757,817 2,691,586 Installation instructions . htm </ a>' & _
'<img width="20" height="22"> <a src="/icons/text.gif" alt="[TXT]" 2732618_readme.htm href="2790817%202732618_readme.htm"> 2790817 </a>' & _
'<img width="20" height="22"> <a src="/icons/text.gif" alt="[TXT]" href="942146.reg"> 942146.reg </a>' & _

Local $aArray = StringRegExp($sTest, "(?i)([^>]+)(?:</\s?a)", 3)

_ArrayDisplay($aArray)

Parsing html with REs is almost always deemed to failure some day.

It's very fragile since web pages evolve constantly and it suffices of the slightliest change in cosmetics (addition of a bold attribute for instance, or insertion of meaningless whitespaces at unexpected places) to make your RE collapse.

Use of _IE* functions makes your scripts much, much more stable when it come to dissect html and friends.

This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.
Another excellent RegExp tutorial. Don't forget downloading your copy of up-to-date pcretest.exe and pcregrep.exe here
RegExp tutorial: enough to get started
PCRE v8.33 regexp documentation latest available release and currently implemented in AutoIt beta.

SQLitespeed is another feature-rich premier SQLite manager (includes import/export). Well worth a try.
SQLite Expert (freeware Personal Edition or payware Pro version) is a very useful SQLite database manager.
An excellent eBook covering almost every aspect of SQLite3: a must-read for anyone doing serious work.

A work-in-progress SQLite3 tutorial. Don't miss other LxyzTHW pages!
SQLite official website with full documentation (may be newer than the SQLite library that comes standard with AutoIt)

Exactly. I've been there before and severly bitten at the same spot :

Maybe this.

#include <array.au3>

Local $sTest = '<img src="/icons/text.gif" alt="[TXT]" width="20" height="22"> <a href="2757817%202691586%20Installation%20instructions.htm"> 2,757,817 2,691,586 Installation instructions . htm </ a>' & _
        '<img width="20" height="22"> <a src="/icons/text.gif" alt="[TXT]" 2732618_readme.htm href="2790817%202732618_readme.htm"> 2790817 </a>' & _
        '<img width="20" height="22"> <a src="/icons/text.gif" alt="[TXT]" href="942146.reg"> 942146.reg </a>' & _
        '<img src="/icons/text.gif" alt="[TXT]" width="20" height="22"> <a href="Windows6.1-KB2757817-x64%20Installation%20instructions.htm"> Windows6.1-KB2757817-x64 Installation instructions.htm </a>' & _
        '<img src="/icons/text.gif" alt="[TXT]" width="20" height="22"> <a href="Windows6.1-KB976932-x64.html"> Windows6.1-KB976932-x64.html </a>'

Local $aArray = StringRegExp(StringReplace($sTest, "%20", " "), 'href="([^"]+)"', 3)

_ArrayDisplay($aArray)

Yes, but i use InetRead, not _IExxxxx :). It was my mistake not clarify

Then this may be of interest (similar to jdelaney's)

#include <IE.au3>

local $sHTML = fileread(@scriptdir & '\test1.txt')

ConsoleWrite(_get_text($sHTML) & @LF)

Func _get_text($html)

    Local $ohtml = ObjCreate('HTMLFILE'), $ret_str = ''

    If Not IsObj($ohtml) Then Return SetError(-1, 0, '')

    $ohtml.open()
    $ohtml.write($html)
    $ohtml.close()

    Local $oeles = _IETagNameAllGetCollection($ohtml)
    For $oele In $oeles
        if $oele.tagname = 'a' then $ret_str &= $oele.innerText & @lf
    Next

    return $ret_str

EndFunc
