RE: Trouble with position!

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]"/>

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
