Parsea a text as a XML document and returns the root element (org.w3c.dom.Element). It is the first step to obtain an element with which to work and be able to apply the DOM functions.
 

1 dom.parse

<dom.parse>
    <text /> !
</dom.parse>

Exceptions

IOException

The text could not be obtained.

org.xml.sax.SAXException

Error of parse, the document does not contain a well-formed text.

javax.xml.parsers.ParserConfigurationException

Error of parse, the document does not contain a well-formed text.

Example

Parsear a file which contains a XML document and get the root element.

Copy
<xsql-script name='dom_parse'>
    <body>
        <set name='root'>
            <dom.parse>
                <file name='f1.xml' type='absolute' />
            </dom.parse>
        </set>

        <println><root/></println>
    </body>
</xsql-script>
Example

Go through an XML from a variable with XML content.

Copy
<xsql-script name='dom_parse'>

   <body>
       <set name='m_xml'>&lt;document>
                           &lt;element>hello&lt;/element>
                           &lt;element>world&lt;/element>
                         &lt;/document>
       </set>


	<set name='hl7_root'>

           <dom.parse><m_xml /></dom.parse>

                 <hl7_root />
            </dom.element.getFirstChildElement>
       </set>
