XML::Reader.

You can create a document from your string:

xp = XML::Parser.new
xp.string = your_string
xml_doc = xp.parse

Hello,

I saw your post searching some help for LibXML.

I'm trying to validate via LibXML::XML::Schema like it's written in the
official documentation:

http://libxml.rubyforge.org/rdoc/classes/LibXML/XML/S...

"""

# parse schema as xml document
schema_document = XML::Document.file('schema.rng')

# prepare schema for validation
schema = XML::Schema.document(schema_document)

# parse xml document to be validated
instance = XML::Document.file('instance.xml')

# validate
instance.validate_schema(schema)

"""


...but there is something wrong about installation because I can't use
the validation method. I don't have it. I was looking around and I can't
see the method anywhere.

Do you have any idea??

P.S. I'm using Leopard as SO and I haven't changed anything about
libxml2.

Thanks in advance,
Raul.
