I've annotated this to show you some of the things that are wrong with your
code, but I haven't tried to correct your errors because I simply can't see
what you are aiming at.

<?xml version="1.0"?>
> <!DOCTYPE xsl:stylesheet SYSTEM "C:\Documents and 
> Settings\ines\Bureau\exemple3\Untitled2.dtd">

The location of the DTD must be a URI, not a filename. Some products let you
get away with this error, but they shouldn't.

> <xsl:stylesheet version="1.0" 
> xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
> xmlns:xlink="http://www.w3.org/TR/xlink" 
> xmlns:gml="http://www.opengis.net/gml" 
> xmlns:redirect="org.apache.xalan.xslt.extensions.Redirect" 
> xmlns:mur="murmur" extension-element-prefixes="mur">

> 	<xsl:output method="xml" 
> doctype-system="D:\mesrecherchesmastere\svg\DTD\svg10.dtd" 
> doctype-public="-//W3C//DTD SVG 20000303 Stylable//EN"/>

> 	<xsl:variable name="boxCoord" select="//gml:Box/gml:coordinates/."/>

The trailing "/." is noise and should be removed.

> 	     <xsl:template
match="//gml:centerLineOf/gml:LineString/gml:coordinates">

The leading "//" is noise and should be removed.

> 		<xsl:variable name="clist" select="."/>
> 		<xsl:variable name="tclist"
select="normalize-space($clist)"/>

> 		<xsl:template match="/">

You can't have one template rule inside another. I don't know what you are
trying to achieve here.

> 			<xsl:variable name="boxCoord"></xsl:variable>

This variable will have a value that is always a result tree fragment
containing an empty string, which doesn't seem very useful.

> 			<xsl:template match="/">

Another nested template! You appear to be confused.

> 		<svg xml:space="preserve" viewBox="{$boxCoord}">
> 			<xsl:apply-templates/>
> 		</svg>
> 	</xsl:template>	
> 	</xsl:template>	
> 	</xsl:template>
