Validating xml with sax parser
The piece of XML to validate is specified in the constructor.
In this section we shall validate the example XML document with XML schema document catalog.xsd, with the SAXParser class. Create a SAXParser object and set the validation mode of the SAXParser object to SCHEMA_VALIDATION, as shown in the following listing: Validates the complete XML document with an XML schema if the parser is able to find a schema.
When using this DTD to validate the input XML document, the following error gets reported: Before a document can be called XML and not csv, simple text or any other format, it needs to support the basic rules as defined by the XML Recommendation, when it adheres to these rules it is said to be Wellformed XML.

What I observe is, irrespective of the size of input XML and schema(.xsd) the XML Parsing and Validation with SAX parser shoots CPU to 100% utilization.
Namespaces have been introduced to XML after the first specification of XML had received the official W3C Recommendation status.
This is the reason why (most of the) XML parser implementations do not support XML Namespaces by default, to handle the validation of XML documents with namespaces correctly it is therefore necessary to configure the underlying parsers to provide support for XML Namespaces.
An XMLSchema object represents the DOM structure of an XML schema document and is created with an XSDBuilder class object.
