Karthik RANGARAJSubject: Xul tree search using XQuery XPath Expression
Author: Karthik RANGARAJ
Date: 02 Jul 2011 06:17 AM
Hi Friends, i have a XUL tree loaded dynamically from XML using XQUERY query type xml(Xpath Expressions).

How can i do a filter/search in XUL tree. I have found some code for custom tree from Mozilla website but that doesn't work with dynamic tree.

When i type something in the text box of search field, it should extract the values in XUL tree, tree cell. How can i write a Xpath expression for filter in xul tree.

I know we have to add a piece of Xpath expression somewhere else in my xul tree template. Because there is no proper tutorial using XQuery Xpath expression in xul tree. I couldn't do it.

Some one please help me to write a Xpath query.t. Thank you friends.


This is my xul code for search bar:[code]
<hbox align="center" id="search-box">
<textbox type="search" oncommand="SearchKeyword(this)"/>
<button id="reloadpage" oncommand="reload()" label="Refresh" disabled="false"/>
<button label="Edit/Save" oncommand="edit();" />

</hbox>
[/code]

This is my XUL tree:

[code]
<treechildren datasources="file://D:/xmlparserinxul/finalversion2.xml" ref="*" querytype="xml">
<template>
<query expr="CONTACT">
<assign var="?pde" expr="PDE-Identity"/>
<assign var="?fname" expr="FirstName"/>
<assign var="?lname" expr="LastName"/>
<assign var="?gmail" expr="gmail"/>
<assign var="?yahoo" expr="yahoo"/>
<assign var="?alcatel-lucent" expr="alcatel-lucent"/>
<assign var="?facebook" expr="URL"/>
<assign var="?id" expr="Facebook-ID"/>
</query>
<action>
<treeitem uri="?">
<treerow>
<treecell label="?pde"/>
<treecell label="?fname"/>
<treecell label="?lname"/>
<treecell label="?gmail"/>
<treecell label="?yahoo"/>
<treecell label="?alcatel-lucent"/>
<treecell label="?facebook" />
<treecell label="?id" />
</treerow>
</treeitem>
</action>
</template>
</treechildren>

</tree>
[/code]

JavaScript:
[code]
function SearchKeyword(oElem)
{

}
[/code]:
