Been trying to get this working for a while, but I have to surrender...

 

My XML:

<?xml version="1.0" encoding="UTF-16"?>
<Surface name="Zone 101_01.01_A_020!" desc="" xmlns="http://www.landxml.org/schema/LandXML-1.2">
	<SourceData/>
	<Definition surfType="TIN" area2DSurf="234921.542328654672" area3DSurf="238197.012906672346" elevMax="11.943587904916" elevMin="-3.839199295337">
		<Pnts>
			<P id="2">214609.472108227172 150506.362479594914 5.162708941504</P>
		</Pnts>
	</Definition>
</Surface>

The attribute I need is "Zone 101_01.01_A_020!".

 

Queries I tried:

/Surface/@name/string()
for $c in /Surface
return data($c/@name)
/Surface/@name

When I test in online extractors, it does work. When I remove the namespace it starts to work, but why?

I'm using FME Desktop 2021.2.6

Can someone please help?

thanks!

Lesson learned, take more time to read the documentation more carefully, as it is described in the first example. 😅

 

Since the top-level node contains the namespace declaration 'xmlns', the namespace must be declared in the query and it must be used to specify every element.
