Android validating sax parser

After applying the patch it is necessary to update also update SAXMemory so that the gc() is executed in the overridden end Document method instead of end Element method.

With the current implementation, I will get the error notification only after the end Element notification, thus too late.

Is there a particular reason to notify the handler in that order, or could it be changed?

Sun's implementation supports any combination of configuration options.

For validation to be possible, the XML document needs to be associated to a DTD or an XML schema.

With Woodstox, for example, I can process my 7 GB file (including validation) with just 64MB of heap. I'll attach a small diagnosis program (SAXMemory Usage.java) that shows that Xerces heap consumption increases inordinately.

This seems to be rather a design issue than the leak, see the logic in the handle Start Element() method in the org.apache.dtd. In the f Element Children array there are all children for the particular element stored as QName objects.Note that tutorial examples given in this section were taken in 2002 using JDK 1.4 and Xerces-J 2.3. But the example Java program can still run using JDK 1.6 and Xerces2 2.9.1 Xerces-J package can also be loaded by the SAXParser Instance() method. The xml is just the root, child element with 3 children repeated.It isn't a huge issue, but the users that will possibly edit the xml file won't have a way to validate (or know how), that is why I was looking into this.I've realized any savings when using map (as suggested in my previous comment) are compensated by quite slow retrieving the value from the map. If tested using SAXMemory Usage.java, decrease the NSIZ setting up to 6.
