Subject: RE: [xsl] Trouble with position! From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Fri, 15 Apr 2005 09:07:58 +0100 |
When the value of a predicate [X] is an integer, it's a shorthand for [position()=X]. So E[position()] means E[position()=position()] which is the same as E[true()], or simply E. Your mistake is in forgetting that the context changes inside the square brackets. So you need to assign a variable to the value of position() outside the predicate, and then use the variable inside the predicate: <xsl:variable name="pos" select="position"> <xsl:value-of select="x/y/z[$pos]"/> Michael Kay http://www.saxonica.com/ > -----Original Message----- > From: Adam J Knight [mailto:adam@xxxxxxxxxxxxxxxxx] > Sent: 15 April 2005 03:44 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: [xsl] Trouble with position! > > Hi all, > > With this xml structure in mind: > <dfile> > <df_column_names> > <df_column name="employee_name" type="hyperlink">Name:</df_column> > <df_column name="department" type="text">Department:</df_column> > <df_column name="position" type="text">Position:</df_column> > </df_column_names> > <df_data_row> > <data_key>1695</data_key> > <df_data>Charles Hilditch</df_data> > <df_data>Processing</df_data> > <df_data>Mill Supervisor</df_data> > </df_data_row> > </dfile> > > I am trying to select the type attribute for a particular > df_data element. > > <xsl:for-each select="./df_data"> > <xsl:value-of > select="/dfile/df_column_names/df_column[position()]/@type"/> > </xsl:for-each> > > My algorithm is simply select the type attribute from df_column whose > position Is equal to current df_data element being processed. > > I keep getting the type attribute for the first db_column name only. > > Thanx to those who respond. > > > Cheers, > Adam
