Re: Questions on reading large xml file using DOM parser

[David N Bertoni/Cambridge/IBM]

Hi,

This makes no sense.  You cannot get the document until the parser is
finished parsing it, so there's no way to use the DOMParser for this.
Also, how can you say the DOM parser no longer needs a particular child?
It's building a DOM representation of the document and that means
everything must be there when it's finished.  Aren't you really saying
_you_ don't need the child anymore?

Why do you insist you need to use the DOM parser?  Not only is this a
perfect case for using a SAX parser, but what you're looking for makes with
the DOM model.

Hi,
I'm trying to parse a large xml file (7MB) using DOM parser ( I have to
use DOM parser). The xml file is like the following:
<root>
<child1> ---------------------------<child1/>
<child2> ---------------------------<child2/>
                         .
                         .
                         .
<childn> ---------------------------<childn/>
<root/>
After the parser read through child1, it does not need it anymore. The
same case as child2 and ... and childn. I know this is a perfect case for
a SAX parser. However, I can't use it. I have to use DOM parser. Is there
any way to remove child1 once the parser finished reading it so that the
memory held by the parser is not too big?

There might be some similar question asked before. However, I can't find
it from the archive. Could you help with some hints?

Thanks a lot!

Lihong
