<TAGVALUE	Attribute Description Table

(r): Attribute or child element is required.

Description

Searches numeric values within a specified element in a metadata document.

Restrictions

• One or two of the operator attributes from the following list must be specified: lessthan, greaterthan, lessthanorequalto, greaterthanorequalto, notequalto, or equalto. If two attributes are specified, they are automatically concatenated together with an "and" operator.

Notes

• TAGVALUE must reference an XML tag that has been indexed as a number, and values in the tag must be numbers. For example, if a tag containing scale information has a value "1:24000", this value is not valid since it is a string. It will not be found by a TAGVALUE search. A valid value would be "24000". For more information on indexing, see Chapter 3 in Creating and Using Metadata Services.
• For searching text values, see TAGTEXT or FULLTEXT.
