Import XML Solaredge

I try via the API of SolarEdge to import data into OH1.

Items I have the following line:

Number lastday "Last day [% .1f W]" (SolarEdge) {http="<[]" }

When I open the URL in a browser, I see the data in XML format.

When I check my transforms through correct this and I get the correct information out.

My transform

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="" version="1.0">

<xsl:output indent="yes" method="xml" encoding="UTF-8" omit-xml-declaration="yes" />

<xsl:template match="/">
	<xsl:value-of select="(//data/value)[last()]"/>

So far no problem I think.

OH gives an error

org.openhab.model.item.binding.BindingConfigParseException: bindingConfig '' doesn't represent a valid in-binding-configuration. A valid configuration is matched by the RegExp '(.*?)(\{.*\})?:(?!//)(\d*):(.*)'

does anyone have an idea?

Your binding steering is malformed. You must provide a break between the URL and the transform, a : I think. Then you need to tell it what sort of transform you want to apply, XSLT(Solar edge.xsl). See the http binding web page for details.
