<p class="MsoNormal">I agree with the other respondents: apart from giving an error if the context item is not a node, "./." is precisely equivalent to ".".<br>
<br>
(Not sure why an XSLT question is appearing on the XQuery list...)<br>
<br>
There's a certain fondness for verbosity in some parts of the XSLT user community. It's quite common to see "./price" where "price" would serve perfectly well, or "price/text()" for "price"; or xsl:element and xsl:attribute used where literal result elements
would do the job, or (my favourite gripe)<br>
<br>
<xsl:variable name="x"><br>
<xsl:value-of select="count(y)"/><br>
</xsl:variable><br>
<br>
where <xsl:variable name="x" select="count(y)"/> would serve the purpose better.<br>
<br>
And of course we've all seen things like <xsl:if test="contains(x, y) = true()">.<br>
<br>
I think some XSLT programmers must be paid by the yard; alternatively the language attracts those who love the sourd of their own keyboard. But "./." isn't an expansion I have seen before.<br>
