The examples in this document reference the customer and customerText tables defined as follows:

CREATE TABLE customer (
   customerID INTEGER,
   customerName VARCHAR(256),
   customerXML XML )
   PRIMARY INDEX (customerID);

CREATE TABLE customerText (
   customerID INTEGER,
   customerName VARCHAR(256),
   customerXMLText CLOB )
   PRIMARY INDEX (customerID);

The examples use a sample XML document in a file named Cust001.xml. The contents of this file are as follows:

<?xml version="1.0" encoding="UTF-8"?>
<Customer>

The sample XML document contains a Customers/Customer/Order/Item hierarchy. The examples use a schema file named customerschema.xsd that specifies the grammar for this XML document. The contents of customerschema.xsd are as follows:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
   <xs:element name="Item">
