RE: [xsl] Copying and updating selectively

["John Reid" <John.Reid@xxxxxxxxxxxxxxx>]

Thanx Américo Albuquerque,

That worked well, and taught me something.

Another q

If I was to add another condition that is higher up the tree how/where
would I best test it
Ie
The same template but this time I am asking only to test those players
where pword a parameter = @pword. This is really 2 problems for me, I
guess I would like to know the best way to pass a parameter to a
template as a condition of entry and to also know how to test further up
the tree.

Non pasaran

John Reid

  <xsl:param name="varFrom" select="'20030809'"/>
  <xsl:param name="varTo" select="'20030812'"/>
  <xsl:param name="varPword" select="'843208'"/>

  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="yes">
    <!-- this variable is been used as a shortcut to current()/@ID in
the
select statement -->
    <xsl:variable name="id" select="@ID"/>
    <xsl:copy>
      <!-- here I'm sellecting all non text nodes, all text nodes if the
current node ID attribute is not between $varFrom and $varTo and all
attribute nodes -->
      <xsl:apply-templates select="node()[not(self::text())] |
text()[not($id &gt;= $varFrom and $id &lt;= $varTo)] | @*"/>
    </xsl:copy>
  </xsl:template>

<player pword="843208">
  <dates>
    <yes ID="20030722" WE="Tu">A</yes>
    <yes ID="20030729" WE="Tu">A</yes>
    <yes ID="20030805" WE="Tu">A</yes>
    <yes ID="20030809" WE="Sa">D</yes>
    <yes ID="20030810" WE="Su">D</yes>
    <yes ID="20030812" WE="Tu">D</yes>
    <yes ID="20030819" WE="Tu">A</yes>
    <yes ID="20030826" WE="Tu">A</yes>
  </dates>
</player>

Will give this result (no D's):
<player pword="843208">

    <yes ID="20030722" WE="Tu">A</yes>
    <yes ID="20030729" WE="Tu">A</yes>

    <yes ID="20030812" WE="Tu"/>

This is a variation of the identity template. Copy all nodes and change
just
that you want to change

  <xsl:param name="varFrom" select="'20030809'"/>
  <xsl:param name="varTo" select="'20030812'"/>


  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="yes">
    <!-- this variable is been used as a shortcut to current()/@ID in
the
select statement -->
    <xsl:variable name="id" select="@ID"/>
    <xsl:copy>
      <!-- here I'm sellecting all non text nodes, all text nodes if the
current node ID attribute is not between $varFrom and $varTo and all
attribute nodes -->
      <xsl:apply-templates select="node()[not(self::text())] |
text()[not($id &gt;= $varFrom and $id &lt;= $varTo)] | @*"/>
    </xsl:copy>
  </xsl:template>


Applied to (the A's is to see if those nodes get copied or not):
<player>
  <dates>
    <yes ID="20030722" WE="Tu">A</yes>
    <yes ID="20030729" WE="Tu">A</yes>
    <yes ID="20030805" WE="Tu">A</yes>
    <yes ID="20030809" WE="Sa">D</yes>
    <yes ID="20030810" WE="Su">D</yes>
    <yes ID="20030812" WE="Tu">D</yes>
    <yes ID="20030819" WE="Tu">A</yes>
    <yes ID="20030826" WE="Tu">A</yes>
  </dates>
</player>

Will give this result (no D's):
<player>
  <dates>
    <yes ID="20030722" WE="Tu">A</yes>
    <yes ID="20030729" WE="Tu">A</yes>
    <yes ID="20030805" WE="Tu">A</yes>
    <yes ID="20030809" WE="Sa"/>
    <yes ID="20030810" WE="Su"/>
    <yes ID="20030812" WE="Tu"/>
    <yes ID="20030819" WE="Tu">A</yes>
    <yes ID="20030826" WE="Tu">A</yes>
  </dates>
</player>
