Problems reading a xml

You must Login before you can answer or comment on any questions.

I have an xml that sometimes comes empty node image, but as I can not control and is not nor as undefined, or as null or as''.

var arrImages = xml.documentElement.getElementsByTagName('Image'); if (arrImages == undefined || arrImages == '' || arrImages == null) alert ('Undefined'); else alert (arrImages.item(0).text)

Any solution??

Try using a try/catch instead.

Hi Raul,

If you have an xml like 

<root attribute='a'></root>
and if you get empty as response 
<root />
 
here you can check
 
if(root.hasAttribute('attribute'))
{
 // true
}
Hope this will solve your prob.
