If you are talking about entity resolution then the xml parser must attempt to resolve the entity to ensure the xml is well-formed.

You can turn off validation, but the parser will still attempt to get the dtd for this purpose.

To get around this, you can try implementing your own entity resolver in java, and just return the entity reference (instead of what it resolves to) or if you are using xerces you can set the feature http://apache.org/xml/features/nonvalidating/load-external-dtd to false which I think will ignore the dtd altogether.

In your case, are you talking entities or character references?  I'm guessing you're using xhtml entities that are not legal in xml - if you could post a sample that fails then it would be a little clearer.
