AlumniYabing,
When exporting results in XML format, you get multiple files, not one file (multiple {GUID} files). Is that what confuses you?
Each file corresponds to the test log of some test item. The MyFinalResult.xml file contains summary information for the run. It also stores a link to the RootLogData.dat file that corresponds to the topmost log node:
MyFinalResult.xml
...
<Nodes version="1">
<Node name="root">
...
<Prp name="root file name" type="S" value="RootLogData.dat"/>
...
</Node>
</Nodes>
The RootLogData.dat file stores links to the results of top-level test items:
RootLogData.dat
<Nodes version="1">
<Node name="root">
<Node name="item 442">
<Node name="children"/>
...
<Prp name="filename" type="S" value="{BA65219D-7BAD-48ED-9CBF-808318A6242E}"/>
...
</Node>
<Node name="item 404">
<Node name="children">
...
<Prp name="filename" type="S" value="{F6769F16-93B0-435B-9C26-BB0E0186F8A2}"/>
...
</Node>
...
The {GUID} files that correspond to these test items store links to the results of the test items that reside on deeper levels. These file names are also {GUIDs}.
The XML format of results is used in cases when you need to process results somehow at later time. If you need visual presentation, export in MHT or HTML formats.
