> Key: XERCESJ-1388
> URL: https://issues.apache.org/jira/browse/XERCESJ-1388
> Project: Xerces2-J
> Issue Type: New Feature
> Components: Other
> Affects Versions: 2.9.1
> Reporter: Radu Preotiuc-Pietro
> Assignee: Khaled Noaman
> Fix For: 2.10.0

>
> When dealing with back-references to groups >= 10, "\" followed by more than one digit must match the largest number, smaller than the total number of groups, that can be constructed by dropping digits from the right.
> So, for instance, \11 must match the 11th capturing group of the expression "^ (#)(a)(b)(c)(d)(e)(f)(g)(h)(i)(j)\11", because there are 11 capturing groups; it must not match the first capturing group ant then the digit "1".
