The element-available() function tests whether a given element is available in this particular XSLT processor. This allows you to design strategies for falling back gracefully if it is not.
Syntax:
boolean element-available(string)
Arguments:
- The name of the element being tested for. The name should be a QName. If the value is not a string, it will be converted to one using the rules of the string() function.
Result:
- True if the element is available, false otherwise.
Defined: XSLT, section 15.
NS support: Supported.
