Update attribute value in XML using QdomDocument supported functions

Hello,

I am using QDomDocument supported functions to update attributes of XML element but not successful :(

ex: sample XML file below

<Terminal>

<address> Some text </address>

<Ethernet port = " " baudrate = " "/>

</Terminal>


With below line, I am able to edit 'address' element text value.

firstChildElement("address").firstChild().setNodeValue("XYZ");



But, I am not able to update attributes value for 'Ethernet' element, I mean I want to update 'port' and 'baudrate' values. Can someone please help me.

I have above question when I am trying to update the existing XML file.

eID_attribute = eID.firstChildElement("Ethernet");
eID_attribute.setAttribute("Port", "XXXX");
eID_attribute.setAttribute("baudrate", "XXXX");
