Error While reading data From XML using JQuery

Question

i have a xml file like

<?xml version="1.0" encoding="ISO-8859-1"?>
<childrens>
<child entity_id="1" value="Root Catalog" parent_id="0">
<child entity_id="2" value="Apparel" parent_id="1">
    <child entity_id="4" value="Shirts" parent_id="2"/>
    <child entity_id="5" value="Pants" parent_id="2"/>
</child>
<child entity_id="3" value="Accessories" parent_id="1">
    <child entity_id="6" value="Handbags" parent_id="3"/>
    <child entity_id="7" value="Jewelry" parent_id="3"/>
</child>
</child>
</childrens>

n have tried to get data where parent_id=2 n have written this jquery code

$(document).ready(function(){
        $.ajax({
            type: "GET",
            url: "test.xml",
            dataType: "xml",
            success: function(xml) {
                $(xml).find('child').attr('[parent_id=3]').each(function(){
                    var id = $(this).attr('entity_id');
                    alert(id);

                });
            }
        });
    });

but it is not working

if i remove .attr('[parent_id=3]') then each id will be alert

Wrong use of attr, the way you used attr('[parent_id=3]') will search attributes with name=[parent_id=3] and if element has such attributes then it string value will be used by each which seems not required here.

Live Demo

Change

$(xml).find('child').attr('[parent_id=3]').each(function(){

To

$(xml).find('child[parent_id=3]').each(function(){
