Don't use get_xpath, use findnodes, as the docs state:

XML::Twig does not provide natively full XPATH support, but you can use "XML::Twig::XPath" to get "findnodes" to use "XML::XPath" as the XPath engine, with full coverage of the spec.

Actually the development version of XML::Twig produces the following message in that situation:

error in xpath expression //OverallConnectionPoolStatus/FlowRater/Name/text() around text() the expression is a valid XPath statement, and you are using XML::Twig::XPath, but you are using either 'find_nodes' or 'get_xpath' where the method you likely wanted to use is 'findnodes', which is the only one that uses the full XPath engine

    Ohhh, now it is working!
    BTW thank you for the wonderful module. It really helping me in saving much more on performance when I am processing big XML files.
    Just a small suggestion, maybe in a new version (or just in the docs) somehow make this more understandable for others, who would like to use this module in a future. Maybe to change the method name to "findnodesWithXpath" or something ...
    but anyway, thank you again.
