Xpath = JxPath

Quite often while implementing   SOAP based service we  need to  traverse   xpath.

So, my XSD looks like this;

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

<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:tns="myorg.xml.com" targetNamespace="myorg.xml.com">

<element name="employeeDetails">

<complexType >

<sequence>

<element name="employee" type="tns:Employee" minOccurs="1" maxOccurs="unbounded"/>

</sequence>

</complexType>

</element>

    <complexType name="Employee">

    <sequence>

    <element  name="employeeId" type="int" />

    <element name="employeeName" type="string" />

    <element name="department" type="tns:Department"/>

    <element name="EmployeeDesignation" type="tns:Designation"/>

    </sequence>

    </complexType>

    <complexType name="Department">

    <sequence>

    <element  name="departmentId" type="int" />

    <element name="departmentName" type="string" />

    </sequence>

    </complexType>

   

   <simpleType name="Designation">

    <restriction base="string">

    <enumeration value="Associate"/>

    <enumeration value="Software Engineer"/>

    <enumeration value="Senior Software Engineer"/>

    <enumeration value="Manager"/>

    <enumeration value="Executive"/>

   

    </restriction>

    </simpleType>

</schema>

And a sample XML:

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

<tns:employeeDetails xmlns:tns="myorg.xml.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="myorg.xml.com Employee.xsd ">

  <employee>

    <employeeId>230</employeeId>

    <employeeName>Jim</employeeName>

    <department>

      <departmentId>1</departmentId>

      <departmentName>IT</departmentName>

    </department>

    <EmployeeDesignation>Associate</EmployeeDesignation>

  </employee>

 

  <employee>

    <employeeId>231</employeeId>

    <employeeName>Tim</employeeName>

    <department>

      <departmentId>12</departmentId>

      <departmentName>Admin</departmentName>

    </department>

    <EmployeeDesignation>Manager</EmployeeDesignation>

  </employee>

</tns:employeeDetails>

JXPath (http://commons.apache.org/jxpath/)  provides APIs for traversal of graphs of JavaBeans, DOM and other types of objects using the XPath syntax. Both child and attribute axis of a node is mapped to Java Beans Properties.
