Need help in displaying XML in JSP

Question

Hi there,
i'm a newbi in XML and Java - I have the following prob, think for most of u nothing very difficult (or better thought so, I've posted this question in different forums here, but nobody answers :)
I get an XML response from a search engine, now I want to display the search result in a jsp.
The result is stored in the session [I hope I figured out correctly ;)]
with the following command ->
this.pageContext.getSession().setAttribute(SEARCHRESULT, dSearchResult);
[its from the java class, which generates the result]
Result example ->
<?xml version="1.0" encoding="UTF-8"?>
<FindSearchResult xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../xml/SearchResult.xsd">
<Result Hits="2" Name="OfficeLand_en_US">
<Items>
<Item Score="250">
<Field FieldNo="0" Name="ProductID">KqvAqAB1Tq0AAADnFthtpZvC</Field>
<Field FieldNo="1" Name="CatalogCategoryID">gh0KAAFvj3wAAADiW8SMtr6o</Field>
</Item>
<Item Score="250">
<Field FieldNo="0" Name="ProductID">4rwKAAFvtNYAAADiwdCMtr6o</Field>
<Field FieldNo="1" Name="CatalogCategoryID">gh0KAAFvj3wAAADiW8SMtr6o</Field>
</Item>
</Items>
<HitDistribution>
<Hit Hits="75" Score="0"/>
<Hit Hits="2" Score="250"/>
</HitDistribution>
</Result>
</FindSearchResult>
How many 'Field' elements exist, depends on the query.
The result example is a response, which is send to my JSP page. It is stored in an variable under the name SEARCHRESULT (it's the result of a query in a search engine).
My JSP page is the page, which should display the searchresult.
So i need to know, how to programm something in my JSP page to check the SEARCHRESULT to display not the whole xml file. I just want to display all Items (compare with result example) -> The name of each existing FieldNo, the Score and the HitDistribution.
Please help me :)

hi there,
first create a xml schema for the xml you will be receiving.
use jaxb or castor with the schema and create a class.
in your jsp unmarshal the xml result you are getting with the class
generated by either jaxb or castor. the class will have methods that return you the required elements.
get to know xml schema better and just a pass thru of jaxb or castor will solve the problem.
