Capture all matching patterns after a string text

I want to capture both values after <ParagraphB>, but I'm currently stuck on only capturing the last match. Here is my regex so far:

<ParagraphB>(?s).*<value>([^\<]*)

<ParagraphA>
<value>12</value>
<ParagraphB>
<value>34</value>
<value>56</value>

Any help is appreciated.

Solution

  • To capture the value multiple times, we need to use the global flag and retrieve the captured group in each match.

    Pattern: (?:<ParagraphB>|\G<\/value>)\s*?<value>([^<]*)

    Explanation: For the first time match, <ParagraphB>. From next iteration, only match if the string starts with </value>

    • (?:<ParagraphB>|\G<\/value>): Match <ParagraphB> or string should start with </value>. \G is for continuing matches.
    • \s* : Non greedy match of any no of space characters
    • ([^<]*) : Capture all characters till <.
