I've discovered a quirk of .Net System.Xml.Xsl.XSLTransfrom that doesn't
seem to exist in the MSXML2 transformation.
When calling a recursive template for the first time, don't pass a parameter
value using a variable with the same name as the parameter. This seems to
cause the original value to remain constant in all recursive calls, even if
you modify that value inside the template. To demonstrate:
<xsl:template match="/">
<xsl:param name="x"/>
<html>
<body>
<xsl:call-template name="recurse">
<xsl:with-param name="x" select="$x"/>
</xsl:call-template>
</body>
</html>
</xsl:template>
<xsl:template name="recurse">
<xsl:param name="x"/>
<xsl:param name="y" select="number(1)"/>
<xsl:if test="number($y)<10">
<xsl:call-template name="recurse">
<xsl:with-param name="x" select="substring-after($x,',')"/>
<xsl:with-param name="y" select="number($y)+1"/>
</xsl:call-template>
</xsl:if>
x=<xsl:value-of select="$x"/>,y=<xsl:value-of select="$y"/><br></br>
</xsl:template>
With .Net XSLTransform, passing
"a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y ,z" to the uppermost
paramter 'x', the ouput of the above is:
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=10
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=9
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=8
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=7
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=6
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=5
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=4
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=3
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=2
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=1
(without the terminating condition on y, this would produce an infinite
loop)
whereas with MSXML2, the output is:
x=j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,y=10
x=i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,y=9
x=h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,y=8
x=g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,y=7
x=f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,y=6
x=e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,y=5
x=d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,y= 4
x=c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z, y=3
x=b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y, z,y=2
x=a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x, y,z,y=1
Aside from this being brought about by lazy parameter naming, is this a bug
in .Net's System.Xml.Xsl.XslTransform?

Yes. This is a bug.
Expected to be fixed in 1.1 SP1
