Need the list of XML parsers

[Venu]

Hi,

I am getting into serious Python programming for Electronic CAD tools,
I am trying to find the best XML parser modules available. I need good
searching capability for attributes, nodes and block of XML. I am
looking for either a recommendation or previous forum links.

Thanks
Venu

lxml is a good XML parser. It supports xpath and IIRC, xquery.

I wrote a blog post about it a while ago -

Hi Venu,
Use element tree module.
This comes with Python itself and does all that you need with presision.
I have already used it and it does a very very good job.
Happy hacking.

Canonical answers: cElementTree and lxml.

The first, if you want to use stdlib tools, the second, if you can afford
external dependencies.

Both are mostly compatible, very fast and memory friendly. lxml has lots of
features in addition.

Using cElementTree, would you be willing show to me how to find the nodes with certain attribute, ie search using attributes and attibute values.
I did not see any example code from the cElementTree official website.

Check out the documentation of ElementTree and lxml.etree. That should get
you going.

lxml is a great one, but it is not simple to install libxml and libxslt on
Linux using user permissions.

Well, you have to build it, obviously. Just pass "--static-deps" to the
build script and it will build and link libxml2 and libxslt automatically
for you.
