APIs for SAX writers

[Duke Hamacher]

I have a situation where I occasionally would like to insert an element in an XML file I'm parsing, while I'm parsing it. Are there any dependable APIs for this? Thanx.

Why would you want to do that? I don't know what the problems is you are trying to solve, but you might want to transform your source xml before parsing it ...

I know, it seems odd, but this world presents odd situations. What is going on is this . . . I have a client who will not necessarily follow our schema (for complex reasons). If they make a certain error, it would be most efficient to correct it on the spot (during parsing) and save the need to communicate the problem back to my client. Certainly, there are other ways fix files, but SAX writing provides the best answer resource and time-wise.

Thanx for repsonding,

To do this during SAX parsing, you'll want to setup a SAX ContentHandler. Look at http://www-106.ibm.com/developerworks/library/x-tiphandl.html for a good explanation of the basics. DeveloperWorks has quite a few good articles on things like this, so their XML section might be worth a more general browse.

If the error is regular enough, it might be cleaner and simpler to do with XSLT as the previous responder suggested. And if it's not, the code to fix it during parsing might also be a bear.
