I'm exceptionally new to XML and XPath and I'm really enjoying
Nokogiri so far. Today I wanted to do something more advanced and I
tried the function 'starts_with' as defined in the XPath 2.0
specifcication. That resulted in a RuntimeError:
RuntimeError: xmlXPathCompOpEval: function starts_with not found

To what extend does Nokogiri support XPath 1|2.0?

starts-with() is actually an XPath 1.0 function. It looks like you're
using an underscore instead of a dash:

We leverage the XPath implementation inside libxml2. libxml2 supports
XPath 1.0.

Hope that helps!
