| Subject: | XPath 'sum' fails due to missing to_number method |
Distribution: XML::XPath-1.12
Perl: 5.6.0

See attached test case. The expected results are:
count of BBB is 3
sum of BBB is 22
Under XML::XPath 1.12 (and previous versions, I assume), the actual results are:
count of BBB is 3
No such method to_number in XML::XPath::Node::ElementImpl at blib/lib/XML/XPath/Function.pm line 360
I added a simple to_number method to my local Element.pm. Patch below:
