Description

This regex extracts Attribute Values from specified Attribute Name.

Only known edge case is if a saml:AttributeValue tag is the first tag in the string, but it shouldn't be the case for SAML responses

It can easily adapted to do the same type of extract from an XML tag containing multiple tags containing values
