getElementsByTagName returning null

Hi,

I'm running a sample dom parser to print a xml by reading each node, element and child, the iteration failed when it reached 100th element
<root>
<test1 data =1>
<a>aa</a>
<b>bb</b>
<c>cc</c>
<d>dd</d>
<e>ee</e>
</test1>
98 times similar test nodes
<test100 data=100>
<a>aa</a>
<b>bb</b> // when reading this tag using the getElementsByTagName the abstarctdom parser returns a NULL.
<c>cc</c>
<d>dd</d>
<e>ee</e>
</test100>
</root>

If this is not the right group please route it to appropriate group, This looks like a bug to me with abstractdom class, because the the code works when we have only 99 elements

Thanks
