Hello tsue,

Have you tried StringRegExp()? This example works fine with your HTML example.

#include <Array.au3>

$fPath = @DesktopDir & 'HTML_Test.txt'

$HTML_text = FileRead($fPath)

$sre_Array = StringRegExp($HTML_text,'IMG SRC\=\"(.*?)\" BORDER',3)

_ArrayDisplay($sre_Array)

for $i = 0 to UBound($array) - 1
    msgbox(0, "RegExp Test with Option 2 - " & $i, $array[$i])
Next

try this:

$array = StringRegExp($HTML_text, '(?s).*?(images.*?jpg).*?', 3, 1)

For $i = 0 To UBound($array) - 1
    MsgBox(0, "RegExp Test with Option 1 - " & $i, $array[$i])
Next

$aImages = StringRegExp($sHTML, "(?i)HREF\s*=\s*\x22(.+\.jpg)", 3)
If Not @Error Then
    For $i = 0 To UBound($aImages) -1
        MsgBox(4096, "Result " & $i+1, $aImages[$i])
    Next
Else
    MsgBox(4096, "Error", "The expression returned error code " & @Error)
EndIf

Another one that might be what you are really needing would be

$aImages = StringRegExp($sHTML, "(?i)<img\ssrc\s*=\s*\x22(.+\.jpg)", 3)
If Not @Error Then
    For $i = 0 To UBound($aImages) -1
        MsgBox(4096, "Result " & $i+1, $aImages[$i])
    Next
Else
    MsgBox(4096, "Error", "The expression returned error code " & @Error)
EndIf

EDIT:

By the way, the test you ran was doomed to failure from the start becuase of all the double quotes in it

"<TD WIDTH="150px" HEIGHT="150px"><A TARGET="_blank" A HREF="images/magic_knight_rayearth-love-alcione_lantys.jpg"><IMG SRC="galeria/_magic_knight_rayearth-love-alcione_lantys.jpg" BORDER="0" ALT="Alcione&Lantys" WIDTH="150" HEIGTH="150"></A></TD>"

In order to use that you would wrap the whole thing in single quotes and do the same in your expression.

Rather than use it in the expression, I prefer to use \x22 to check if a double-quote appears at a given position.

thanks it worked, and thanks geosoft for the other information too

now im trying to understand how does it work

ok so (?s) makes the . next to match anything even newlines and * makes it repeat,

the next i dont really understand ?(Find the smallest match instead of the largest after a repeat character) but i found that if i take it out it only gives me 1 result

so all of this part was to search unti it finds everything inside () ?

now insede () it will search from images to jpg?

and why does it has to be added .*? again?

can u help me to understand this. thanks

See attached (if I can get the attacment thingy to work).

thank you, for this all of this information, i found that it can give the same result as this

$array = StringRegExp($HTML_text, '(?s)(images.*?jpg)', 3, 1)

from what i have read, i havent found the reason why you add .*? outside ()

thanks

[GEOSoft]

The *? tells PCRE to find the smallest match which is particularly important when using (?s). Uing your first post as an example, if you did not add the *? it would return

images/magic_knight_rayearth-love-alcione_lantys.jpg"><IMG SRC="galeria/_magic_knight_rayearth-love-alcione_lantys.jpg" BORDER="0" ALT="Alcione&Lantys" WIDTH="150" HEIGTH="150"></A></TD>

<TD WIDTH="150px" HEIGHT="150px"><A TARGET="_blank" A HREF="images/magic_knight_rayearth-love-alcione_sierra02.jpg"><IMG SRC="galeria/_magic_knight_rayearth-love-alcione_sierra02.jpg" BORDER="0" ALT="Alcione&Sierra" WIDTH="150" HEIGTH="150"></A></TD>

<TD WIDTH="150px" HEIGHT="150px"><A TARGET="_blank" A HREF="images/magic_knight_rayearth-love-alcione_zagato01.jpg"><IMG SRC="galeria/_magic_knight_rayearth-love-alcione_zagato01.jpg

in element 0 of the array. Using the ? forces it to stop matching after the first .jpg and start searching for the next match.
