xmldom getlength gives me only 1?

hi here is a snippet of my xml; when i do this in my pl.sql i get a count of 1? why is this so? i want to know the total no of nodes within <Parameters> so that i can run the loop.
nl := xmldom.getElementsByTagName(doc, 'Parameters');
len := xmldom.getLength(nl);
htp.p('Length : ' || len);

The problem is the sample data has only one "Parameters" node, so length=1 is correct. for the nodelist of "Parameters"

If you want the count of all nodes within Parameters you will need to get a DOMElement and call getchildrenbyname, or otherwise iterate through the nodes inside that node and count them

what do you mean by i need to get a DOMElement? how can i do that?
basically i need to find a child inside Parameters node
e.g. <RangeMeasured>
<Name>TrackError25[C]To-5[C]</Name>
<Min>0.031</Min>
<Max>0.041</Max>
<Units>dB</Units>
</RangeMeasured>
i need to find TrackError25[C]To-5[C]... and if exists then i need to change the min and max.
would you be able to help on this?
