XMLDOM Question

[George Jewell]

Hello,

I have a block of xml and need to determine if a specific element exists.
(Using IE 6).

I might have the following:

<Results>
<Personal>
<Lastname>Doe</Lastname>
<Firstname>John</Firstname>
<Middlename>Q</Middlename> (this element may or may not exist,
depending on the results)
</Personal>
</Results>

Using the XMLDOM, is there a property or method I can use to determine if,
say, the <Middlename> element even exists in the block?

Thanks.

You can check
xmlDocument.getElementsByTagName('Middlename').length
to find out how many elements with the tag name 'Middlename' exist.
If you have a certain element already you can also appy that method to
the element say you have
personalElementObject
you can then check
personalElementObject.getElementsByTagName('Middlename').length
