XML

<ns1:BoardTestXMLExport xmlns:ns1="http://tempuri.org/BoardTestXMLExport.xsd" numberOfIndictedComponents="5" testerTestStartTime="2021-01-30T00:31:32.000+07:00" testTime="2021-01-30T00:31:22.000+07:00" repairStationId="HCMINGAOI11" testStatus="Reviewed Passed" testerTestEndTime="2021-01-30T00:31:37.000+07:00" numberOfIndictedPins="0" numberOfComponentsTested="319" numberOfJointsTested="0" numberOfDefects="5" repairStatus="Reviewed Passed">
    <ns1:BoardXML imageId="3" serialNumber="21028217724" assemblyRevision="ING-296244891AE_M-A-B" boardType="ING-296244891AE_M-A-B" boardRevision="1607419487000"/>
    <ns1:StationXML testerName="HCMINGAOI05" stage="V510"/>
</ns1:BoardTestXMLExport>

I get Element numberOfComponentsTested and show to label : 319

I want to load the next file this number will add up with the previous result. example file 1 numberOfComponentsTested = 319 , next file numberOfComponentsTested = 200;

label total will show 519.You know what I mean?
How do I calculate that?

And?

What have you tried?
Where are you stuck?
What help do you need?

What does it do that you didn't expect, or not do that you did?
What have you tried to do to find out why?
Are there any error messages, and if so, where and when? What did you do to make them happen?

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with - and we have no access to yoru code, or the XML data, so we have no real idea what data you are working with, or how you are dealing with it!

You're saying you didn't write any code and you want someone else to do it: read one or more XML file while summing "numberOfComponentsTested".

Uhhh...seems simple enough. Create a variable, like totalComponents, and, I don't know, add the total count from each file you load to it? When you're done loading your files, show the value of totalComponents in the label.

If you're storing the "value" in the label, hoping to add another value to it, you're doing it wrong. The UI controls are there to show and manipulate the state of your data model, not to store values for it.
