public class Parse extends SystemFunction
This class implements the saxon:parse() extension function, which is specially-recognized by the system because it needs access to parts of the static context

  • Method Details

    • call

      public NodeInfo call(XPathContext context, Sequence[] arguments) throws XPathException
      Evaluate this function call at run-time
      Parameters:
      context - The XPath dynamic evaluation context
      arguments - The values of the arguments to the function call. Each argument value (which is in general a sequence) is supplied in the form of an iterator over the items in the sequence. If required, the supplied sequence can be materialized by calling, for example, new SequenceExtent(arguments[i]). If the argument is always a singleton, then the single item may be obtained by calling arguments[i].next(). The implementation is not obliged to read all the items in each SequenceIterator if they are not required to compute the result; but if any SequenceIterator is not read to completion, it is good practice to call its close() method.
      Returns:
      an iterator over the results of the function. If the result is a single item, it can be returned in the form of a SingletonIterator. If the result is an empty sequence, the method should return EmptyIterator.getInstance()
      Throws:
      XPathException - if a dynamic error occurs during evaluation of the function. The Saxon run-time code will add information about the error location.

    • setXMLReader

      protected ParseOptions setXMLReader(Configuration config, ParseOptions source) throws XPathException
      Set the XML parser to be used, if different from the default XML parser
      Parameters:
      config - the Saxon configuration
      source - the ParseOptions object to be updated with the selected parser
      Throws:
      XPathException - if the selected parser cannot be loaded
