IMO we can ask to install xmllint as a pre-requisite. Using a regular expression to extract the values from an XML might be error prone since the regular expression is vulnerable to spaces or lines breaks which can be added in future releases.
But xmllint is a proper XML parser. So it will work as long the schema is the same.
