Problems with text() and REXML

[Kenneth McDonald]

I'm finding that in REXML, the XPath selector "//abstract//style"
correctly selects nodes in the tree, but "//abstract//style//text()"
does not then extract the text from those nodes. Is this a known
problem with XPath in Rexml?

Thanks,
Ken

You're abusing "//". This works for me

#!/bin/env ruby

require 'rexml/document'

doc = REXML:ocument.new <<XML
<root>
<abstract>
<style>
the text
</style>
</abstract>
</root>
XML

REXML::XPath.each(doc, '//abstract/style/text()') do |elm|
p elm
end
