Errors in XML documents will stop your XML program.
The W3C XML specification states that a program should not continue to process an XML document if it finds an error. The reason is that XML software should be easy to write, and that all XML documents should be compatible.
With HTML it was possible to create documents with "errors" (like dropping end tags). One of the main reasons that HTML browsers are so big and incompatible, is that they have their own ways to figure out what a document should look like when they encounter an HTML error.
With XML this should not be possible.
