tag name <item> gives syntax error when used with XQuery

[Maheshkumar]

I have a schema with an element name as . I was able to insert XML docs using the xplorer into the schema.
When i try to query tag using XQuery from (Interactive Interface) i get syntax error.

for $b in (input()/doc_root/item
return $b

The above gives syntax error. Please help me out on this.Is there any limitation not use as a tag in the XML.

Thanks

Reserved keywords in XQuery

Tamino XQuery 4 follows the W3C XQuery working draft from August 2002, which uses reserved keywords. This means that the keywords of the language cannot be directly used as identifiers. Workaround: The use of a prefix token “:” is allowed on unprefixed QNames to visually distinguish tokens that are spelled the same as keywords. For instance, the following is a path expression containing the element names for, if, and return: :for/:if/:return.

And sure enough, ?item? is in the list of reserved names (see http://w3.org/TR/xquery/#id-reserved-fn-names). So your query should be:

for $b in input()/doc_root/:item
return $b
