XML Input / first character is missing

Hi together,

I'am trying to get some XML input into Splunk, but everytime the first character ("<") is missing. Due to this, Splunk cannot read XML correctly: (on two different sources)

from example-source: www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml

this input:
<xml version="1.0" encoding="UTF-8"?><gesmes:Envel...
is getting this:
xml version="1.0" encoding="UTF-8"?><gesmes:Envel...

Is there anyone who knows why the first character is missing?

Best regard Steffen
