I have a gml file and i want read it using svg tool, but I don't know what are the steps to realise this and it's necessary to convert it in xslt.
and what software can I use to convert it directly.
Usually GML provides for the graph structure only. In order to get an SVG, you have to generate shapes for nodes and edges and place them onto the virtual canvas. In general, this is a very difficult task and not suitable for implementation in XSLT. It may be solvable if you know that your input graph has one of a few simple structures.
There are very few graph layout libraries available. You best bet is probably GraphViz. You'll have to transform your input GML into GraphViz's input language. The most recent GraphViz releases can generate SVG directly.
If GraphViz's capabilities are too limited for your problem, try one of the few free layout libraries on SourceForge (but they all have inconveniet limits) or get a commercial tool.
