The rst-generator gives you now a hint what's going on:
Bad reference: 'method.RegEx.search_all' in file: ../modules/regex/doc_classes/RegExMatch.xml
grep 'method.RegEx.search_all' ../modules/regex/doc_classes/RegExMatch.xml
Contains the results of a single regex match returned by [method RegEx.search]
and [method.RegEx.search_all]. It can be used to find the position and range of the match
and its capturing groups, and it can extract its sub-string for you.
