>             Project: Xerces2-J
>          Issue Type: Bug

>    Affects Versions: 2.10.0

> In org.apache.xerces.impl.xpath.regex.RegexParser
> I think the processBackreference() method has a bug.  
> I think this line:
>     if ('1' <= ch && ch <= '9') {
> Should be:
>     if ('0' <= ch && ch <= '9') {
> In order to correctly process backreferences where a subsequent digit is 0.
