Python SAX parser says XML file is not well-formed
I would second recommendation to try to parse it using another XML parser. That should give an indication as to whether it's the document that's wrong, or parser.
Also, the actual error message might be useful. One fairly common problem for example is that the xml declaration (if one is used, it's optional) must be the very first thing -- not even whitespace is allowed before it.
I stripped some tags that I thought were unnecessary from an XML file. Now when I try to parse it, my SAX parser throws an error and says my file is not well-formed. However, I know every start tag has an end tag. The file's opening tag has a link to an XML schema. Could this be causing the trouble? If so, then how do I fix it?
Edit: I think I've found the problem. My character data contains "&lt" and "&gt" characters, presumably from html tags. After being parsed, these are converted to "<" and ">" characters, which seems to bother the SAX parser. Is there any way to prevent this from happening?
