DataTable Control: XML Data with XPath

This DataTable is populated with XML data where the schema is defined using XPath-syntax locators. Please note that namespace support is not implemented at this time.

View example in new window.

When working with XML data, use the DataSource's useXPath property to enable XPath syntax in your locator strings.
