XML DOM - Validate XML

XML DOM validates the XML syntax

An XML error will stop your XML program

Errors in the XML documentation will stop your XML program.

The W3C XML specification states that if an error is found, the program should not continue to process the XML document. T he reason is that XML software should be easy to write and all XML documents should be compatible.

HTML make it possible to create documents with "errors" such as missing end tags. O ne of the main reasons HTML browsers are so large and incompatible is that they have their own way of understanding what a document should look like when they encounter an HTML error.

With XML, this should not be possible.
