is matlab's xmlread using too much memory?

I am running into a memory problem when trying to read in large (not huge!) xml files. Estimating Java memory usage is tricky, but it seems that

dom=xmlread('somefile.xml');

takes way more memory than it ought to. I know how to set the default available Java memory in the preferences, but I am al开发者_JAVA百科ready up to 512MB and not even my full "resolution" xmls yet. And memory usage definitely does not scale well with file size.

If it will help I could provide a link to a ~5MB xml file that takes ~60MB of Java memory with xmlread.

Any ideas? Thanks in advance, -n

You could try the XML IO Tools from the file exchange as an alternative way of reading your file.

Also take a look at the Mathworks doc on Resolving "out of memory" errors.
