XMLPARSE

Syntax

Description of xmlparse.eps follows
Description of the illustration xmlparse.eps

Purpose

XMLParse parses and generates an XML instance from the evaluated result of value_expr. The value_expr must resolve to a string. If value_expr resolves to null, then the function returns null.

  • If you specify DOCUMENT, then value_expr must resolve to a singly rooted XML document.

  • If you specify CONTENT, then value_expr must resolve to a valid XML value.

  • When you specify WELLFORMED, you are guaranteeing that value_expr resolves to a well-formed XML document, so the database does not perform validity checks to ensure that the input is well formed.

Examples

The following example uses the DUAL table to illustrate the syntax of XMLParse: 

SELECT XMLPARSE(CONTENT '124 <purchaseOrder poNo="12435"> 
   <customerName> Acme Enterprises</customerName>
   <itemNo>32987457</itemNo>
   </purchaseOrder>' 
WELLFORMED) AS PO FROM DUAL;
 
PO
-----------------------------------------------------------------
124 <purchaseOrder poNo="12435">
   <customerName> Acme Enterprises</customerName>
   <itemNo>32987457</itemNo>
   </purchaseOrder>
