Validating web xml
By default, the validation of a document is done by using a processor (XML parser, XSLT transformer, XQuery engine, etc.) to analyze the current file.The validation scenario allows you to specify a set of files to validate, the processor to use for each file, and whether or not to perform continuous validation.The Oxygen Validation Scenarios are very powerful and solve numerous important issues when working with XML markup and XML-related technologies.
Suppose that you are working with a large XML document that you decide to split into multiple files and use external entities to merge those files into a master document.
When creating XML documents, errors can be introduced.
Working with large projects or a vast number of files increases the probability that errors will occur.
The W3C XML specification states that a program should stop processing an XML document if it finds an error.
The reason is that XML software should be small, fast, and compatible.
