...with many such property elements inside the elem1 element.

I want to print the value of the 'value' attribute for the property element that has a name of 'name1'. So far I've been doing it this way:

<xsl:for-each select="./elem1/property[./@name='name1']">
   <b><xsl:value-of select="@value"/></b>
</xsl:for-each>

But it seems like there should be a more concise way of doing this, especially since I know that my input document will only have one property element with a matching "@name='name1'" attribute.

Use a lookup key table:


  <xsl:key name="props" match="property" use="@name"/>
  ...
  <b><xsl:value-of select="key('props','name1')/@value"/></b>

I hope this helps.
