I figure there might be something very wrong with my assumptions, but I couldn't find any specific explanation in the relevant SO questions I browsed, nor in other online literature. XMLInput Factory xif = XMLInput Factory(); // not sure if this is required? IS_VALIDATING, "true"); // adding dtd XMLResolver( new XMLResolver() ); XMLStream Reader reader = null; try finally Also, according to this question, you will need to use a different St AX implementation as the default doesn't support validation.
Like suggested in the answer to that question, I tried using woodstox by adding the woodstox 5.0.3 jar and the stax2 api 4.0.0 jar to my classpath (and adding the doctype with the system identifier to the XML) and got the expected exception: has no attribute "blah" at [row,col ]: [5,5] at
On the other hand, an XML is considered valid if it follows the rules specified in the DTD or XSD.
we look at both DTD and XSD validation package com.jaxp; import

Note that it is in accordance with described above as it defines the ‘title’ element (see line 4 below) instead of ‘salary’ element.
Then try to validate invalid (see line 46 below)and verify that the validation fails .

Problem Sta X doesn't seem to validate anything even when provided a valid DTD, and the XML file does not match the schema defined in the DTD.
