by Ram Peters April 7, 2007

<Library> <DVD id="1"> <title>Breakfast at Tiffany's</title> <format>Movie</format> <genre>Classic</genre> </DVD> <DVD id="2"> <title>Borat</title> <format>Movie</format> <genre>Comedy</genre> </DVD> </Library> How to parse this xml received from a client using lxml? I will be using lxml objectify. First I need to get first child (This is where I am stuck.) and assign it to the python model. Get second child and assign it to the python model, so on. I looked at the documentation, it's kind of hard to grasp for a newb. Thank you.

[lxml-dev] Document is not valid XML Schema
by Jeff Cheng April 5, 2007

April 5, 2007

I am trying to validate XML files against their respective schemas. However, lxml complains that the schemas are not valid. Python 2.5 (r25:51908, Mar 13 2007, 08:13:14) [GCC 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)] on cygwin Type "help", "copyright", "credits" or "license" for more information. >>> from lxml import etree >>> f = file("linux-definitions-schema.xsd") >>> xmlschema_doc = etree.parse(f) >>> xmlschema = etree.XMLSchema(xmlschema_doc) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "xmlschema.pxi", line 61, in etree.XMLSchema.__init__ etree.XMLSchemaParseError: Document is not valid XML Schema The schemas are from Mitre (http://oval.mitre.org/language/download/schema/version5.2/index.html#do wnloads) and are assumed to be valid. I am using python-2.5, lxml-1.2.1, and libxml2-2.6.26 on cygwin. Any help would be greatly appreciated.

[lxml-dev] lxml objectify

<Library> <DVD id="1"> <title>Breakfast at Tiffany's</title> <format>Movie</format> <genre>Classic</genre> </DVD> <DVD id="2"> <title>Borat</title> <format>Movie</format> <genre>Comedy</genre> </DVD> </Library> How do you represent DVD id=1 and it's elements, and DVD id=2 and it's elements as child of root "Library"? Like this:? from lxml import etree from lxml import objectify root = objectify.Element("Library") child[1] = objectify.Element("DVD", id="1") root.new_child = child[1] Thank you
