When I call the XSLT using Saxon9, I get:
C:\>type foo.DOT.txt | "C:\Program Files\ATT\Graphviz\bin\dot.exe" -Tsvg -o foo.svg
C:\>java.exe -jar C:\saxon9.jar -s:C:\foo.svg -xsl:C:\notugly.xsl -o:C:\foo-notugly.svg
Warning: at xsl:stylesheet on line 3 of file:/C:/notugly.xsl:
Running an XSLT 1.0 stylesheet with an XSLT 2.0 processor
java.net.ConnectException: Connection timed out: connect
Transformation failed: Run-time errors were reported
The input SVG displays fine for me. I tried each of the HTTP URL/URIs in the SVG and XSLT and was able to reach them. I can do plenty of other XSLT processing uning Saxon9, so the installation seems to be ok. Any ideas what's going on and how to fix it?
