Hi Michael,

Thanks for your reply. So is there any way to specify CDATA datatype in schema. ie. I want to know is there any datatype to specify the particular element is CDATA (as like xsd:string etc.,). If its there then probably I can do change in the schema for that particular element.

Hi. Thx for your reply.

CDATA can be used anywhere, around any text in your document. The schema doesn't have to permit it. It's not a datatype, it's just an alternative way of escaping special characters: instead of

<a>x &amp; y</a>

you can write

<a><![CDATA[x & y]]></a>

As far as the schema is concerned, and as far as the receiving application is concerned, these should be 100% equivalent.

ok..So there is no way to specify in xsd, whether a particular xml element can have '&','<' characters..Is it right?

XSD constrains the logical content of the element, not its escaped lexical form. You can ban "<" by writing a pattern facet in the schema, and this will ban all forms of expressing "<" in the input, for example
