[xsl] variables

Hi,

Is it possible to make this two lines into one. (somehow to match @label
against current node @uri without creating new variable $current_section)

<xsl:variable name="current_section"><xsl:value-of
select="@uri"/></xsl:variable>

<xsl:for-each
select="document($menue_doc)//*[@label=$current_section]/descendant::section
">
