write xml elements only if a feature attribute has a value

hello,

I am trying to write inside an xml file elements only if a feature attribute has a value.

I have 2 shp files :

In first file I have "Eticheta" feature with names of the street.

In second file I have "label" feature with attributes values are the same as "Eticheta " from the first file. Here, in the second file I have also "NR" which.

I am trying to write in XML numbers for streets and I need to write the numbers on each street.

I used an if-then-else statement that writes out the numbers only if street from first file is exactly like street from second file.

in my XMLTemplate, in subtemplate I have:

{ if( fme:has-attribute({fme:get-attribute("label")}) eq fme:has-attribute({fme:get-attribute("Eticheta")}) )

then

{fme:process-features("ADRESA")}

but fails to write data inside xml file.

errors from log:

XMLTemplater (XMLTemplaterFactory): An error occurred while parsing the 'ADRESE' sub-template

XMLTemplater (XMLTemplaterFactory): A fatal error has occurred. Check the logfile above for details

XMLTemplater (XMLTemplaterFactory): A fatal error has occurred. Check the logfile above for details

A fatal error has occurred. Check the logfile above for details

Can you please help me with this issue?

Thank you.
