Parsing empty XML nodes in JavaScript

Hi there;

I have the following problem. I am using one of the many javascript XML parsing scripts available around the Internet, but the parsing fails when it reach an XML child node that is empty, as in the example below:

<FirstName>John</FirstName>
<MiddleInitial></MiddleInitial>
<LastName>Smith</LastName>

John Smith does not have a middle initial. When the parsing scripts I tried reach this node, it fails with a message such as "Object Required" or some other error message.

I tried the following commands to no avail:

x[i].childNodes[j].firstChild.length == 0
x[i].childNodes[j].firstChild.nodeValue == ""

but it always fail.

What I need is for a way to recognize that that particular field is empty and allow me to put a space or a &nbsp; in its place without crashing.

Any ideas are welcome.

Thanks for your time. :confused:

// Try this guys:

if (xml.getElementsByTagName('job_number')[i].hasChildNodes())
{

rowData += xml.getElementsByTagName('job_number')[i].firstChild.data;

}
else
{

rowData += '';

}

This works to me....

temp=nodes[i].firstChild;

if (document.getElementById(id)!=null && temp!=null)

Hope u can use it....
