[lxml-dev] ElementTree in the standard library!
by Martijn Faassen 20 Dec '05

20 Dec '05

Hi there, As many of you probably have already seen, ElementTree and cElementTree will be in the standard library of Python as of the next release of Python. This is good news for lxml, as it means that even more people will be exposed to the ElementTree API which lxml is implementing! People who then need more support for XML technologies will find their way to lxml. Hm, perhaps we can even get a link in the Python documentation. :) Regards, Martijn

[lxml-dev] underscores in arguments
by Martijn Faassen 20 Dec '05

20 Dec '05

Hi there, Stephan, I noticed that in your branch (now on the trunk) you prefixed the 'path' and 'namespaces' arguments to the 'xpath' function with underscores. I am going to revert that, as I consider keyword parameters an important feature of Python and I don't see a reason to declare a form of privacy for these argument names. Still, I'm curious as to the motivation for this change? Regards, Martijn

Hi, all! Can anyone explain me why this monstrous setup.py in trunk is better than attached one? -- Andrey Tatarinov <elephantum(a)cyberzoo.ru>

[lxml-dev] How to create an empty doc
by Werner F. Bruhin 17 Dec '05

17 Dec '05

Sorry for this basic question, but I just can't figure it out. I am trying to figure out which tool to use for XML, so I try out different things currently with amara and lxml. I started with amara as it has a little bit more documentation, i.e. sample code, which makes things a lot easier for people like me - THIS is not a complaint. So with amara I can do: doc_header = u'''?twcb version=1.7; xsd=wineXML.xsd?''' doc2 = binderytools.create_document(doc_header) doc2.xml_append(doc2.xml_element(u"wine")) doc2.wine.xml_append(doc2.xml_element(u"name")) doc2.wine.name = u'A wine name' etc etc .... I found the Element and SubElement (methods?) but I can't find the equivalent of create_document or something similar. Could anyone point me to some documenation with samples? Thanks and best regards Werner

[lxml-dev] XML schema question
by Werner F. Bruhin 16 Dec '05

16 Dec '05

O.k. I got past my initial install problems - thanks to Steve's help. I build a schema (information on a wine) using Altova XMLSpy home edition and it validates it. I can also use this schema with JAXFront (from xcentric) to generate a GUI for it. When I do the following: schema = file(r'C:\Dev\TheWineCellarBook\xml\test\winexml.xsd') xmlschema_doc = etree.parse(schema) xmlschema = etree.XMLSchema(xmlschema_doc) I get "etree.XMLSchemaParseError: Document is not valid XML Schema" Can I get more detail from lxml on what the problem in my schema is? Or is there another tool (instead of Altova) I should use to validate my Schema? Thanks for any hints or tips Werner

[lxml-dev] XML Schema Info
by Dethe Elza 14 Dec '05

14 Dec '05

Hi folks, When using an XML Schema for validation, can the Schema itself be queried? For instance, given an element, can I ask what child elements would be legal (or mandatory)? --Dethe This [the adoption of open source software] isn't just my idea, or Brazil's idea. It's the idea of our time. The complexity of our times demands it." --Gilberto Gil, Brazilian Minister of Culture

[lxml-dev] merging the ElementTree changes
by Martijn Faassen 13 Dec '05

13 Dec '05

Hi there, Stefan, all, I've been pondering over the changes Stefan implemented to make the ElementTree class work more like the original elementtree implementation, where multiple ElementTree's can exist for a single tree without affecting tree structure. I would like to see fakeRootDocument to be changed so that the fake document temporarily also fixes the parent reference, so that libxml2 is never exposed to inconsistent document structures. Of course now that I think of it, doing that may cause problems with namespace lookups and the like... Ugh... :( Anyway, still, I've decided the benefits outweigh the costs, even though I do feel uncomfortable about it. If you, Stefan, are willing to merge this set of changes before I do, then please do so. Otherwise I'll try to get around to it at the end of this week. Regards, Martijn
