How To Use Regular Expression To "capture/parse" The String Between 2 Strings ?

[microsoft 0]

Hello,

 

Me and my friend are working on a project and we need to know how to capture/parse a string between 2 strings.

 

<div class="phone">+4921661305247</div>

 

We would like to capture/parse +4921661305247 no matter what it is.

If +4921661305247 is present multiple times on the html source, it must only capture/parse the first occurrence.

 

Any help would be greatly appreciated !!

no need for regular expression

 

ifyou just have strings exactly like above,not scraping a webpage then theres a function their called strip tags it will get the innertext of html tags

 

otherwise

load html("<div class=\"phone\">+4921661305247</div>
<div class=\"phone\">+4921661305247</div>
<div class=\"phone\">+4921661305247</div>
<div class=\"phone\">+4921661305247</div>")
add item to list(%phoneNumber,$scrape attribute($element offset(<class="phone">,0),"innertext"),"Don\'t Delete","Global")

Hi,

there are many ways to achieve this.. nothing wrong with any of them

here is the regex tho

(?<=>).*?(?=<)

gets between > and <

if u are using from a body of text just make it more unique and add more

 

(?<="phone">).*?(?=<)

or (?<="phone">).*?(?=</div)

 

don't need the plus?

(?<="phone">+).*?(?=</div)

 

here is my cheat sheet I got from this forum somewhere

(?=ABC)      - Positive lookahead. Matches a group after your main expression without including it in the result.
 
(?!ABC)      - Negative lookahead. Specifies a group that can not match after your main expression (ie. if it matches, the result is discarded).
 
(?<=ABC)     - Positive lookbehind. Matches a group before your main expression without including it in the result.
 
(?<!ABC)     - Negative lookbehind. Specifies a group that can not match before your main expression (ie. if it matches, the result is discarded).
 
(?<=ABC).*?(?=ABC) - Extracts the text between specified goups.

 

here is how I test it

Hope this helps,
