622 views

I am facing below error while validating XML file using Java utility, below is error message :

An invalid XML character (Unicode: 0x{2}) was found in the value of attribute "{1}" and element is "1a".

for validation I have used XMLspy however it has gave up to open file because of its huge size, please suggest how we can find this invalid character.

When the message is actually displayed, {2} and {1} should have been replaced with the Unicode hex value of the character and the the name of the attribute respectively. Those would tell you what to look for and where to look.

For huge documents, you may be better off using SAX-based processing (or one of the other event-driven systems) rather than DOM-based parsing, so you can decide what information needs to be kept, versus what can be processed immediately and/or discarded. If you do need a DOM, you may need to alter your Java configuration to obtain more heap or stack memory; that's typically done with -Xmx and =Xms options.
