regex-normalize

[陈琛]

hi,all:
        The regex-normalize.xml file can be used to attempt to normalize
these variants to a canonical form to prevent duplication.

ve been using:
<regex>
  <pattern>;*jsessionid*=[^=\?/\&]+$</pattern>
  <substitution></substitution>
</regex>
<regex>
  <pattern>;*jsessionid*=[^=\?/\&]+(\?.*)</pattern>
  <substitution>$1</substitution>
</regex>

is it right？

but in the search have problem：[Fatal Error] :24:32: The entity name must
immediately follow the '&' in the ent
ity reference.
