How to get the length of sub children? 1

[chandranam]

Hi,

I am new to the XML. Learning from all tutorial site.

I want to count the number of sub-children with in a child. Also when i used the xmlDoc.documentElement.childNodes[1].childNodes.length, i got 9 instead of 4. How to count the sub-children length (of element book)?

Below is the xml code I am using.

<?xml version="1.0"?>

Either you mean you got 7 instead of 4 or you mean nothing.

[1] This shows you what is going on for mozilla-series of browser.
[tt]
var cnodes=oroot.childNodes[1].childNodes;
for (var i=0; i<cnodes.length;i++) {
alert('['+(i+1)+'] type:'+cnodes.nodeType+';'+
((cnodes.nodeType==3)?'nodeValue: '+escape(cnodes.nodeValue):'nodeName: '+cnodes.nodeName));
}
[/tt]
[2] nodeType 1 for element node; 3 for text node. Element node has nodeName well-defined, text node has nodeValue well defined.

[3] The parsing engine for the firefox etc has ignorable whitespace preserved by default. Some engine has the contrary as default such as ie (msxml2).
