yikes! - looks like the simplest way is to have:
<xsl:template match="name">
<xsl:for-each select="ancestor-of-self::*">
<xsl:value-of select="name()" /><xsl:text>/</xsl:text>
</xsl:for-each>
<xsl:value-of select="." />
</xsl:template>
That won't work if you want to generate a path that's independent of the
namespace context. If you want the path expression to be
context-independent then you need to generate steps of the form
*[local-name()='x' and namespace-uri()='y']
Also, the code above generates a path such as a/b/c/d which will select
many elements, whereas you probably want one that selects a single
element such as a[3]/b[2]/c[89]/d[1]. But in this case the "tumbler"
path of the form *[23]/*[2]/*[17] is simpler, and avoids namespace
problems entirely.
As you see, there are multiple solutions to this requirement - which is
because there are actually a number of different requirements. This is
why there is no standard function.
