Summary: XML schema namespace declarations make XPATH return nil

Initial Comment:
XML schema namespace decl cause XPATH expressions to return nil. Example below.

For some schema foo:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="foo">
        <xs:complexType>
            <xs:sequence minOccurs="0" maxOccurs="1">
                <xs:element name="bar"   minOccurs="1" maxOccurs="unbounded">
                    <xs:complexType ><xs:simpleContent > <xs:extension base="xs:int"></xs:extension></xs:simpleContent></xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

(basically elem:foo => elem:bar  => content:int )


And this script:

#require 'rubygems' # uncomment if libmlx-ruby installed via gems
require 'xml/libxml'
d = XML::Document.file ARGV[0]
r = d.find(ARGV[1]).first
puts "#{r.class} ::=> #{r}"
r.each { |e| puts "\t#{e.name} = #{e.content}" if e.element? }



This XML file does not work:

<?xml version="1.0" encoding="UTF-8"?>
<foo xmlns="file:/Volumes/DATA/Src/quanto/rampy/test/test.xsd" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="file:/Volumes/DATA/Src/quanto/rampy/test/test.xsd">
    <bar>2147483647</bar>
    <bar>2147483647</bar>
    <bar>2147483647</bar>
</foo>

But this one does:

<?xml version="1.0" encoding="UTF-8"?>
<foo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="file:/Volumes/DATA/Src/quanto/rampy/test/test.xsd">

    <bar>2147483647</bar>
    <bar>2147483647</bar>
</foo>

Message:
This isn't a bug.  The default namespace attribute does not have a name, but is a namespace so it's required for the find.  So in the case of the xml which "does not work," you'll need to name the default namespace, e.g.: #find('foo:bar', 'foo:file:/Volumes/DATA/Src/quanto/rampy/test/test.xsd').  Where 'foo' is whatever name you decide to give the default namespace in this call.

See http://libxml.rubyforge.org/rdoc/classes/LibXML/XML/XPath/InvalidPath.html

# Since the getManufacturerNamesResponse element uses a default
 # namespace we first have to give it a prefix and register
 # it with the xpath engine.
 doc.find('//ns:getManufacturerNamesResponse',

Summary: "property" method not recognised on LibXML::XML::Node

Initial Comment:
My hard disk recently died so I had to do a fresh install of all my gems including libxml-ruby (I installed 0.8.3). I can't get the old version number, as the hard disk really is dead, but it was probably 0.5.? . This new install broke some previously fine libxml-ruby based code: 

- Now, any use of node.property("name") (e.g. model.property("name")) produces an error like:

undefined method `property' for <model name="Any"/>:LibXML::XML::Node

- However, changing these calls to the node["name"] format (in this case model["name"]) fixes the problem

node.property("name") still appears to be valid in the API docs, and I can't find any indication that it has been deprecated or anything.

Message-ID: <5d3a66f30810100505r9b1c385vd11aece201a803c0@mail.gmail.com>

I am trying to install libxml-ruby for Ruby 1.9 under Debian. There is no
Debian libxml-ruby1.9, so I typed the following command:

sudo gem1.9 install libxml-ruby

The result is the following error:

In file included from libxml.c:5:
ruby_libxml.h:10:18: error: util.h: No such file or directory

I tried changing util.h to ruby/util.h in ruby_libxml.h , but I just got
another error:

ruby_xml_xpath_context.c: In function
'ruby_xml_xpath_context_register_namespaces':
ruby_xml_xpath_context.c:212: error: 'struct RHash' has no member named
'tbl'


What is going on? Is this a problem with my system or with the gem? I have
not done anything unorthodox with my Ruby installation, so I suspect the
latter. Please advise.

Initial Comment:
Installing the gem on a Mac under MacPorts, with Ruby 1.8.6, I get the following error while the extension is building:

  Makefile:106: *** missing separator (did you mean TAB instead of 8 spaces?).  Stop.

A quick look at the generated libxml/Makefile reveals it is has multiple command lines that begin with spaces instead of a tab, which is illegal syntax.

Thanks! I just installed that, and it worked. One caveat: I had to
change line 12 of /usr/local/lib/site_ruby/1.9.0/libxml.rb from

require  'libxml_ruby'

to

require  'i486-linux/libxml_ruby'

I also need to launch irb1.9 as follows:

irb1.9  -I /usr/local/lib/site_ruby/1.9.0/

and then I have to use

require 'xml/libxml'

instead of the more customary

require 'libxml'

Other than that, everything works well, I think.

Ah, you are using the LibXML namespace at the toplevel. Just do:

  require 'xml'

This is equivalent to:

  require 'libxml'
  include LibXML

'xml/libxml' is just there for backward compatibility with how it used
to be required. Ultimately it will be deprecated.

Subject: [libxml-devel] Encoding Problem
Message-ID: <C51B6E38.342D8%Peer.Allan@canadadrugs.com>

We have some data coming from a database using latin1 encoding (which we
can?t change).  When we try to insert that data into a libxml doc the
scripts locks up so badly we have to kill the process manually.  If we do a
conversion on the string (String#toutf8) it works.  Setting the encoding of
the document does not help either.

Here is some code,

>> doc = LibXML::XML::Document.new
>> doc.root = LibXML::XML::Node.new("person")
>> doc.root << lname = LibXML::XML::Node.new('last_name')
>> lname << "Farr?s"

There is no output from this, it just hangs.  The key to remember is the
"Farr?s" is latin1 encoded from MySQL.  If it is UTF-8 the code will work.
The worst part is that it runs right on one server and does not run on
others.  Could there be a library issue?  This is also running under Rails
2.1 if that makes any difference.

Thanks.

Summary: Memory leak with Node.prev and Node.remove!

Initial Comment:
Memory usage of Ruby increases when I execute a script like below. 
---
require 'xml/libxml'

doc = XML::Document.new()
doc.root = XML::Node.new('root')
root = doc.root
root << child = XML::Node.new('child')
(1..100000).each {|i|
  a = XML::Node.new('dummy')
  child.prev = a
  a.remove!
  if i % 100 == 0
    GC.start
    # show memory usage in unix environment.
    puts `ps alx | grep #{$$} | awk '{printf ("%d\t%s\n", $8,$13)}'`
  end
}

Summary: XML::Reader does not work with sockets

Initial Comment:
I tried with the two following programs:
A server:
#!/usr/bin/ruby -w

require 'rubygems'
require 'xml'
require 'socket'


server = TCPServer.new(22222)
while session = server.accept
  reader = XML::Reader.io(session)
  loop do
    rsl = reader.read
    puts rsl
    break if rsl != 1
    puts reader.expand
  end
  session.puts 'ok'
  sleep 1
  session.close
end
# end-of-server
and a client:
#!/usr/bin/ruby

require 'socket'

t = TCPSocket.new('localhost', 22222)

t.puts '<doc><a>k</a></doc>'
puts t.gets
# end-of-client

Output from server:
Entity: line 1:
parser
error :
Extra content at the end of the document

^
-1

I tried different platforms (RH9, CentOS 5.1 and Fedora8).
libxml-ruby-0.8.3
Various libxml2 versions

Subject: [libxml-devel] UTF-8 problem
Message-ID: <458EB412-7AB1-4609-A898-EC47DF85A1A3@mudynamics.com>

I'm trying to input and output special characters, but I'm getting  
parse errors from libxml.

Code snippet:
         node = LibXML::XML::Node.new 'node'
         node.content = '&#1;'
         doc = LibXML::XML::Document.new
         doc.encoding = 'UTF-8'
         doc.root = node
         xml = doc.to_s true, 'UTF-8'

         parser = LibXML::XML::Parser.new
         parser.string = xml
         doc = parser.parse
         p doc.root.content

The first part sets xml to:
<?xml version="1.0" encoding="UTF-8"?>
<node>\1</node>

Where \1 is the byte 1.

The second part tries to parse this.  But libxml gives this error on  
the call to Parser.parse:
Entity: line 2:
parser
error :
internal error
<node></node>
       ^
Entity: line 2:
parser
error :
Extra content at the end of the document
<node></node>

I'm using libxml-ruby 0.8.3 and libxml2 2.6.30.

Any ideas?

Thanks,
David

Subject: [libxml-devel] [ANN] nokogiri 1.0.0 Released
Message-ID: <20081030171546.GA452@mac-mini.local>

nokogiri version 1.0.0 has been released!

* <http://nokogiri.rubyforge.org/>
* <http://github.com/tenderlove/nokogiri/wikis>
* <http://github.com/tenderlove/nokogiri/tree/master>

Nokogiri (?) is an HTML, XML, SAX, and Reader parser with XPath and CSS
selector support.

### FEATURES:

* XPath support for document searching
* CSS3 selector support for document searching
* XML/HTML builder
* Drop in replacement for Hpricot

Nokogiri parses and searches XML/HTML faster than Hpricot, and also has
correctly implemented CSS3 selector support as well as XPath support.

  * http://gist.github.com/18533

Nokogiri also features an Hpricot compatibility layer to help ease the change
to using correct CSS and XPath.

### SYNOPSIS:

  require 'nokogiri'
  require 'open-uri'
  
  doc = Nokogiri::HTML(open('http://www.google.com/search?q=tenderlove'))
  
  ####
  # Search for nodes by css
  doc.css('h3.r a.l').each do |link|
    puts link.content
  end
  
  ####
  # Search for nodes by xpath
  doc.xpath('//h3/a[@class="l"]').each do |link|
    puts link.content
  end
  
  ####
  # Or mix and match.
  doc.search('h3.r a.l', '//h3/a[@class="l"]').each do |link|
    puts link.content
  end

Changes:

### 1.0.0 / 2008-07-13

* 1 major enhancement

  * Birthday!

* <http://nokogiri.rubyforge.org/>
