[libxml-devel] Patch/Question about xmlAttr

[Dan Janowski]

Hi,




Here is an illustration:

require 'rubygems'
require 'libxml'

d=p.parse
irb(main):007:0> d.root.properties
=> name = actid
irb(main):008:0> d.root.properties.next
=> nil

This should yield the "type" attribute.



require 'libxml_so'

d=p.parse
irb(main):004:0> d.root.properties
=> #<XML::Attr:0x7e888>
irb(main):005:0> d.root.properties.name
=> "name"
irb(main):006:0> d.root.properties.next.name
=> "type"
irb(main):007:0> d.root.properties.next
=> #<XML::Attr:0x67188>
irb(main):009:0> d.root.properties.next.name
=> "type"

The problem seems to be the use of:

  rxa->attr = xmlCopyProp(attr->parent, attr);

xmlCopyProp seems to disconnect attr->next in the copy



Unless there is some problem with this, here is a patch for it.

I have just started using libxml2 for ruby and have come to a problem. Attribute traversal is broken. Only the first attr is accessible from .properties. p=XML::Parser.string(%q{<element name="actid" type="xs:positiveInteger"/>}) I have modified the ruby_xml_attr.c and ruby_xml_node.c, the same run yields this: p=XML::Parser.string(%q{<element name="actid" type="xs:positiveInteger"/>}) In addition to which, I do not know why it would need to copy instead of just use the xmlAttrPtr from the model.
