How can I read child node names and their values in XML without specifying the tag name?
Question
Here, I want to loop through the <detail> elements. Although I can specify the <detail> tag name in my code, I can't use the tag names of the children. I want to know the tag names of those elements and their values.
How can I loop through them and do this?
<?xml version="1.0" encoding="utf-8" ?>
<body>
<detail>
<FirstName>t1 </FirstName>
<LastName>t2</LastName>
<Company>t3</Company>
<Country>t4</Country>
<Proviance>MP</Proviance>
<city>indore</city>
</detail>
<detail>
<FirstName>t5 </FirstName>
<LastName>t6</LastName>
<Company>t7</Company>
<Country>t8</Country>
<Proviance>t9</Proviance>
</detail>
<detail>
<FirstName>t10 </FirstName>
<LastName>t11</LastName>
<Company>t12</Company>
<Country>t13</Country>
<Proviance>t14</Proviance>
</detail>
</body>

How about;
var details = xml.getElementsByTagName("detail");
for (var i = 0; i < details.length; i++) {
if (details[i].childNodes) {
for (var j = 0; j < details[i].childNodes.length; j++) {
var detail = details[i].childNodes[j];
if (detail.nodeType === 1)
alert( "details node " + (i + 1) + ": " + detail.nodeName + "=" + detail.firstChild.nodeValue );
}
}
}
