XML Processing

[Roman]

Is there a package that converts a string that contains special
characters in xml to to literal value. For instance, converts string
http://myhome/&param to http://myhome/&param.

Thanks in advance

I've seen examples using the HTMLgen module. But here's another script
I just found:

I would think that you could use regular expressions too.

Both strings in your example are exactly the same, unless I'm missing
something.

Robert, your newsreader/mail program is converting the HTML/XML entity codes into the corresponding character so you're not seeing the plain text version of what the OP posted. He's asking for code to convert XML entities like '&' into their escaped strings.

I believe xml.sax.saxutils.encode() is what the OP is looking for:
'http://myhome/&param'

I would reccommend against using the example above or using regular expressions, since both are likely to miss corner cases, and the stdlib has an encode function that's already designed for this task

http://docs.python.org/lib/module-xml.sax.saxutils.html

The encode() function in xml.sax.saxutils also is extensible, should you run into any entities that it fails to escape in the current implementation.

import xml.sax.saxutils

print xml.sax.saxutils.escape("I'm a happy & friendly guy, and 1 < 3 -
never forget that!")

Yes, I am an idiot.

! Unproved, as Scotsmen are wont to say.

This and similar questions arise frequently enough that I recommend
