Validate XML string against XSD by using Jaxen

[Rajeevr]

Hi Jaxen Users,

I have two basic questions about Jaxen:

Q1. I need to validate a string which contains the data in XML format against a given XSD file by using Jaxen. How this can be done?

XML string can be like this:
<?xml version="1.0"?>
<dictionary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="dictionary.xsd">
        <!-- dictionary_invalid_xsd.xml
                Copyright (c) 2002 by Dr. Herong Yang
        -->
        <word acronym="yes">
                <name>XML</name>
                <definition reference="Herong's Notes">
                        eXtensible Markup Language.
                </definition>
                <update date="2003-23-12" />
        </word>
        <word symbol="true">
                <name></name>
                <definition>
                        Mathematical symbol representing the "less than" logical
                        operation, like: 12.
                </definition>
                <definition>
                        Reserved symbol in XML representing the beginning of tags,
                        like:
                        <![CDATA[<p>Hello world!</p>]]></definition>
                <update />
        </word>
        <word symbol="false" acronym="false">
                <name>extensible</name>
                <definition>Capable of being extended.</definition>
        </word>
</dictionary>

XSD is like this:
<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <xsd:element name="dictionary" type="dictionaryType"/>
        <xsd:complexType name="dictionaryType">
                <xsd:sequence>
                        <xsd:element name="word" type="wordType" maxOccurs="unbounded"/>
                </xsd:sequence>
        </xsd:complexType>
        <xsd:complexType name="wordType">
                <xsd:sequence>
                        <xsd:element name="name" type="xsd:string"/>
                        <xsd:element name="definition" type="definitionType" maxOccurs="unbounded"/>
                        <xsd:element name="update" type="updateType" minOccurs="0"/>
                </xsd:sequence>
                <xsd:attribute name="acronym" type="xsd:boolean" use="optional"/>
                <xsd:attribute name="symbol" type="xsd:boolean" use="optional"/>
        </xsd:complexType>
        <xsd:complexType name="definitionType" mixed="true">
                <xsd:attribute name="reference" type="xsd:string"/>
        </xsd:complexType>
        <xsd:complexType name="updateType">
                <xsd:attribute name="date">
                        <xsd:simpleType>
                                <xsd:restriction base="xsd:string">
                                        <xsd:pattern value="\p{Nd}{4}-\p{Nd}{2}-\p{Nd}{2}"/>
                                </xsd:restriction>
                        </xsd:simpleType>
                </xsd:attribute>
        </xsd:complexType>
</xsd:schema>

Q2. I had done this validation with Xerces. Please also suggest me which methodology is the better one -Jaxen or Xerces?

I'm not sure you'll get much response here until you indicate what your
question has to do with XPath, which is what Jaxen implements?

It can't. That's not what Jaxen does. Try javax.xml.validation instead.
