Lost with extracting a String into a variable with StringRegExpReplace

5 posts in this topic

Hello,

i have a xml file with the following content:

<item Property="Windows 7 Professional"  >
<item Property="Name" Value="Windows 7Professional x64 Service Pack 1"  />
<item Property="Features" Value="Terminal Services in Remote Admin Mode, 64 Bit Edition, Media Center Edition, Multiprocessor Free, OEM-Version"  />
<item Property="Edition Type" Value="Professional"  />
<item Property="Edition ID" Value="X15-37341"  />

From this file i want to extract the following string: Windows 7Professional x64 Service Pack 1

I have tried to extract it with StringRegExpReplace, but it did not work.

#Include <File.au3>
#Include <Array.au3>
$file = "C:tmpos.xml"
$xml_file = FileOpen($file, 0)
$string = StringRegExpReplace(FileRead($xml_file), '<item Property="Name" Value="([^"]*)"  />', "$1")
MsgBox(0,"Info", $string)  

Can somebody help to figure out the right regular expression? Thanks.

Hello,

Try this RegExp:

$string = StringRegExpReplace(FileRead($xml_file), '(?s).+Name.+?Value=\"(.+?)\".+', "$1")

One more thing, remember to use FileClose if you use FileOpen

Regards,

It works. Thank you very much sahsanu. Just one question: i'm new to StringRegExpReplace an I was thinking that the variable $1 is a back reference to the result of the first bracket, so why is $1 working and i don't have to use $2. Can you please point this out? Thanks again.

There is only one capturing group in your pattern. Read help again and realize that (?s) is an option.
