XMLValidate (Magic xpa 4.x)

Validates an XML document against its schema. The XML’s schema can be specified inside the XML document using one of the following:

  • The attribute xsi:noNamespaceSchemaLocation= or xsi:SchemaLocation=

  • An optional (2nd) parameter to the function.

Syntax:

XMLValidate (XML [,XSD schema Url])

Parameters:

XML – A BLOB variable (the XML content).

XSD schema Url – URL (http or local) of a schema file.
If the schema has a targetNamespace, the 2nd parameter (if specified) must have the target namespace prefixed before the schema location, separated by a space.

For example:

XMLValidate (File2Blb ('my.xml'), 'MY_NS http://srvr/my.xsd') , the same as if the schemaLocation was specified in the XML document itself.

MY_NS – The namespace for the given XSD file.

Spaces in the schema path must be escaped.

For example:

XMLValidate (File2Blb ('my.xml'), 'MY_NS http://my%20srvr/my.xsd')

Returns:

Logical (‘TRUE’ – valid, ‘FALSE’ – invalid).

  • If no schema was specified, the XML file is considered valid as long as the schema location is specified in the XML file.

  • If only warnings were found, the file is considered valid.

Note:

During runtime, each XMLValidate call will clear all error(s) of a former XMLValidate call, before execution.

Exceptions:

This function is not supported for Rich Client tasks.

Examples:

Verify ‘Invalid’ XMLValidate(File2Blb(‘my.xml’),’http://srvr/my.xsd’)

XMLValidate (xml-content) – e.g. XMLValidate (A) – A is a BLOB
Validate using 'schemaLocation’ – if ‘schemaLocation’ is missing – returns ‘FALSE’

XMLValidate (xml-content, schema-url) – e.g. XMLValidate (A, ‘http://server/a.xsd’) Always validate using schema-url (i.e. ignore ‘schemaLocation’)
