RE: GML to svg

I copied your stylesheet and data file and ran the transformation. Here are the problems the Saxon processor reported:

>From your stylesheet:

As others have commented, the backslash in this URL is invalid,
<xsl:transform xmlns:xsl="http:\\www.w3.org\1999\XSL\Transform" 
and should be replaced by the forward slash,
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 

Your <xsl:transform> element needs a version attribute. I altered it so,
<xsl:transform version="1.0" ...

Your declaration of this variable contained a space in the name, rendering it invalid,
<xsl:variable name="viewBox Value">,
I changed it so,
<xsl:variable name="viewBoxValue">

That cleared up another error that stated you hadn't declared the variable $viewBoxValue.

Finally I go the error that stated that the namespace prefix "fn" had not been declared and you have used it twice.

That's as far as I can go with it. Try fixing those problems and report back.

Subject:   GML  to svg

Hello,
I always have a same problem: how trasform a gml file to svg.I have a gml file validated with xmlspy, and i want tranform it in svg format to visualise the map (using xmlspy), this map should contain two lines when one represent the road and the other represent the river. I tried to use your suggestion for the xslt file but the result is a html file not a svg file,  from this can you look my following files, to help me found the error:
