how to get values depending on the attribute

vidhya · July 7th, 2005, 04:40 PM

i have an xml that looks like

<contractions elementType="H">
    <description>(3s) -> [2s]</description>
    <contraction shell="S">
      <matrix rows="2" columns="2" dataType="double">
5.447178 0.156285
0.824547 0.904691
       </matrix>
    </contraction>
    <contraction shell="S">
      <matrix rows="1" columns="2" dataType="double">
0.183192 1.000000
       </matrix>
    </contraction>
</contractions>

<contractions elementType="N">
    <description>(3s) -> [2s]</description>
    <contraction shell="S">
      <matrix rows="2" columns="2" dataType="double">
5.447178 0.156285
0.824547 0.904691
       </matrix>
    </contraction>
    <contraction shell="S">
      <matrix rows="1" columns="2" dataType="double">
0.183192 1.000000
       </matrix>
    </contraction>
</contractions>

now i need to get the shell value (ie : S) and the matrix node values
ie(0.183192 1.000000 and 5.447178 0.156285 0.824547 0.904691 ).
I need to get the shell and matrix node values for the elementtype H only.can someone help me out with this

the xsl now looks like
    <xsl:template name="getElementShellType">
            <xsl:param name="Values"/>
        <xsl:if test="$Values">
        <xsl:for-each select="$Values">
             <xsl:value-ofselect="@elementType"></xsl:value-of>
                              <xsl:value-ofselect="@shell"></xsl:value-of>
         </xsl:for-each>
        </xsl:if>
            <xsl:text> </xsl:text>
        </xsl:template>

can someone help me out with this

I don't like the XML, better to have each matrix value in a separate element. Given this XML:

Code:

<root>
  <contractions elementType="H">
    <description>(3s) -> [2s]</description>
    <contraction shell="S">
      <matrix rows="2" columns="2" dataType="double">
        5.447178 0.156285 
        0.824547 0.904691 
      </matrix>
    </contraction>
    <contraction shell="S">
      <matrix rows="1" columns="2" dataType="double">
        0.183192 1.000000 
    </matrix>
    </contraction>
  </contractions>
  <contractions elementType="N">
    <description>(3s) -> [2s]</description>
    <contraction shell="S">
      <matrix rows="2" columns="2" dataType="double">
5.447178 0.156285 
0.824547 0.904691 
       </matrix>
    </contraction>
    <contraction shell="S">
      <matrix rows="1" columns="2" dataType="double">
0.183192 1.000000 
       </matrix>
    </contraction>
  </contractions>
</root>

This stylesheet gives the values. I don't know how you're passing $Values, it must be a nodeset not a string to do a for-each.

Code:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text" />
  <xsl:template match="/">
    <xsl:call-template name="getElementShellType">
      <xsl:with-param name="Values" select="'H'" />
    </xsl:call-template>
  </xsl:template>
  <xsl:template name="getElementShellType">
    <xsl:param name="Values" />
    <xsl:variable name="contractions" select="/*/contractions[@elementType = $Values]" />
    <xsl:for-each select="$contractions/contraction">
      <xsl:text>Shell:#xa0;</xsl:text>
      <xsl:value-of select="@shell" /><xsl:text>#x0d;</xsl:text>
      <xsl:text>Matrix:#xa0;</xsl:text>
      <xsl:value-of select="matrix" /><xsl:text>#x0d;</xsl:text>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>
