@andreone: Thanks for the info and the welcome, I'll create a new topic next time. =) @FranciscoR: That's what I don't get, I pasted the whole html code in Expresso... I'll use the first expression I posted, it's similar to yours but without the "?". Thanks for answering.

Hi FranciscoR and dutchclimber, I am new to Ketarin and really appreciate your efforts! Currently I am trying to learn regular expressions and I got stuck with the following: Webpage: http://www.cpuid.com/cpuz.php Extracted code: [...]<b>CPU-Z 1.51 .zip</b>[...] With the following expression I am able to extract the string "1.51" both from Ketarin and Expresso: (?<=CPU-Z\s)[0-9.]+(?=\s.zip) But this one only works in Expresso: (?<=CPU-Z\s).+(?=\s.zip) Could someone explain to me why the second expression doesn't work with Ketarin? Thanks!
