From 4d15e619eb1838daafd1510e86c1c8076fb9b227 Mon Sep 17 00:00:00 2001 From: kou Date: Sun, 22 Apr 2018 08:09:04 +0000 Subject: rexml: Fix XPath bug of /#{ELEMENT_NAME} It doesn't mean that all elements which name "ELEMENT_NAME" with any namespace URI including null namespace URI. It means that all elements which name "ELEMENT_NAME" with null namespace URI. https://www.w3.org/TR/1999/REC-xpath-19991116/#NT-NodeTest > if the QName does not have a prefix, then the namespace URI is null > (this is the same way attribute names are expanded). We need to use "*[local-name()='#{ELEMENT_NAME}']" for all elements which name "ELEMENT_NAME" with any namespace URI including null namespace URI in XPath 1.0. But it's inconvenient. So this change includes "*:#{LOCAL_NAME}" syntax support that is introduced since XPath 2.0. * lib/rexml/parsers/xpathparser.rb: Support "*:#{LOCAL_NAME}" syntax that is introduced since XPath 2.0. * lib/rexml/xpath_parser.rb: * Fix namespace URI processing for "#{ELEMENT_NAME}". Now, "#{ELEMENT_NAME}" doesn't accept elements with null namespace URI. * Add "*:#{LOCAL_NAME}" support. * test/rexml/test_contrib.rb, test/rexml/test_core.rb, test/rexml/xpath/test_base.rb: Follow this change. * test/rexml/test_jaxen.rb: Fix namespace processing. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63236 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- test/rexml/test_contrib.rb | 2 +- test/rexml/test_core.rb | 20 ++++++++++---------- test/rexml/test_jaxen.rb | 2 ++ test/rexml/xpath/test_base.rb | 1 + 4 files changed, 14 insertions(+), 11 deletions(-) (limited to 'test/rexml') diff --git a/test/rexml/test_contrib.rb b/test/rexml/test_contrib.rb index 8462b3c23f..28b96a4972 100644 --- a/test/rexml/test_contrib.rb +++ b/test/rexml/test_contrib.rb @@ -451,7 +451,7 @@ EOL end def test_external_entity - xp = '//channel/title' + xp = '//*:channel/*:title' %w{working.rss broken.rss}.each do |path| File.open(File.join(fixture_path(path))) do |file| diff --git a/test/rexml/test_core.rb b/test/rexml/test_core.rb index 0071063128..b2e5299f39 100644 --- a/test/rexml/test_core.rb +++ b/test/rexml/test_core.rb @@ -877,18 +877,18 @@ EOL EOL # The most common case.
