I'd like to suggest two new methods for LibXML::XML::XPath::Object.
The first is simply a #to_s method that returns a concat string of all
nodes. Eg.
xml = XML::Document.string("<r><b>1</b><b>2</b></r>")
bes = xml.find('b')
bes.to_s #=> "<b>1</b><b>2</b>"
Currently #to_s is the same as #inspect, which isn't useful.
The second is to add #find, so that we can do sub-searches on the
nodes. Eg.
xml = XML::Document.string(%{<r><b>1</b><b id="q">2</b></r>})
bes = xml.find('b')
bes.to_s #=> "<b>1</b><b id=\"q\">2</b>"
qbs = bes.find("[...@id='q']")
qbs.to_s #=> "<b id=\"q\">2</b>"
Thanks,
Tom
