I would like to add three different sets of info/data to a existing xml file: 
<exec>
    <tc id=""></tc>
</exec>

[download]
To produce the following xml file: 
<exec>
    <dut mac="" ip="" model="" firmware=""/>
    <tc id="" version="" date="" desription/objective="">
        <ts id="" desription="" date="" expected_result="" result=""/>
    </tc>
</exec>

[download]
The first <dut> will only be added once but there will be severeal instances of <tc> and every <tc> will have one or more <ts> What I got so far is that I have to start read the existing xml file. But wondering how I best insert the data to the xml file? And how often should the xml file be saved?
