      <h1>saxon:parse()</h1>
      <p><b>saxon:parse($xml as xs:string) ==&gt; document-node()</b></p>
      <p>This function takes a single argument, a string containing the source text of a well-formed
XML document. It returns the document node (root node) that results from parsing this text. It throws
an error if the text is not well-formed XML. Applications should not rely on the identity of the
returned document node (at present, if the function is called twice with the same arguments, it
returns a new document node each time, but this may change in future).</p>
      <p>This function is useful where one XML document is embedded inside another using CDATA,
or as an alternative way of passing an XML document as a parameter to a stylesheet.</p>
      <p>A dynamic error is reported if the supplied string is not well-formed (and namespace-well-formed) XML.
An XML declaration may be included, but is not required: if it is present, the encoding declaration will
be ignored, since the document is supplied in character form rather than in binary.</p>
      <p>The XML parser that is used will be the one nominated to the Saxon <code>Configuration</code>
 as the parser for source documents. Validation against schemas or DTDs, and whitespace stripping, will take place
 according the settings in the <code>Configuration</code> object; if called from XSLT, the <code>xsl:strip-space</code>
 and <code>xsl:preserve-space</code> settings in the stylesheet are also taken into account.</p>
