The 'position' of the parent node is something altogether different because it is relative to some other list of nodes that only you know about. For example, maybe you want the position of the parent relative to its element siblings, or relative to all its siblings (regardless of type), or relative to its ancestors... > If the data looks > like: > > <data> > <item> > <name>xyz</name> > <lineitem> > <cost>24</cost> > <lineitem> > <cost>30</cost> > <item> > <name>abc</name> > <lineitem> > <cost>24</cost> > <lineitem> > <cost>30</cost> > > and I use a for loop as to output HTML: > > <xsl:template match="item"> > <xsl:for-each select="lineitem"> > For item #<xsl:value-of select="position()"> > <xsl:value-of select="../name"> > the cost for lineitem is <xsl:value-of select="cost"> > </xsl:for-each> > </xsl:template> > > Here, the output I want should have the item position rather than the > lineitem position but because of the location it gives me lineitem position, > which is correct within the loop construct.

Stick it in a variable before you change the context: <xsl:template match="item"> <xsl:variable name="itempos" select="position()"/> <xsl:for-each select="lineitem"> <xsl:value-of select="concat('For item #',$itempos,' ',../name, ' the cost for lineitem is ',cost,' ')"/> </xsl:for-each> </xsl:template> - Mike ____________________________________________________________________________ mike j. brown | xml/xslt: http://skew.org/xml/ denver/boulder, colorado, usa | resume: http://skew.org/~mike/resume/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
