Case-insensitive XML Parsing

[C. R. Sandeep]

Hi,

I am using the xml.dom.minidom module to do some XML parsing. Is
there any way I can set an option to do case-insensitive parsing? I
have a lot of files with inconsistent tag names and I need to parse
them in Python. I checked the Python Global Module Reference but
couldn't find any relevant information. Also, I do not want to use
xmllib at this time (which, I think, supports case-insensitive parsing
- not sure of this though).

Thanks in advance,

Sandeep.

Sorry for omitting context.

Perhaps the OP is parsing HTML and needs something like Tidy (if you're
wondering why I didn't include a link it's for 2 reasons: I'm lazy and
google exists)?

If your tag names are inconsistant, then xml probably won't help.

OTOH, if they differ only by case, then do a prepass on the data to
normalize the case of the tags.

In that case (no pun intended) it isn't XML you are parsing.

But be warned...

Tidy removes the entity references that are not HTML builtin entities. Even
in XML mode 8((

Not built-in, no. You could do the following things:

- lower-case the entire input before parsing;
- if you know the complete list of tags in advance:
replace all misspellings of these tags before parsing.

Another option, if you have PyXML, is to use sgmlop. sgmlop's
SGMLParser is case-insensitive. You need to create an sgmlop SAX
driver (i.e. "xml.sax.drivers2.drv_sgmlop"), and pass this to
minidom.parse.

Notice that the parser will then operate in SGML mode, which may or
may not work for your input.

Martin

As Steve said, if the tags are case-insensitive, it's not XML.
In any case, I believe the PyRXP parser by http://www.reportlab.com
has a CaseInsensitive flag, though you should know it's not a DOM
parser, but a specialized Python one (very fast and efficient, mind you,
but it's not DOM).
