Building Table based on child values

Question

Hi I'm trying to return a table based on a sample of the following input:

<Table TableLevel="1" TableNumber="1" TableTitle="">
  <TableRow TableRowLevel="1" RowTitle="" TableRowNumber="1" class="Even">
    <TableHeader width="33" class="tableheadercell">
      <Paragraph>Account Name</Paragraph>
    </TableHeader>
    <TableHeader width="10" class="tableheadercell">
      <Paragraph>Type</Paragraph>
    </TableHeader>
    <TableHeader width="57" class="tableheadercell">
      <Paragraph>Additional Information</Paragraph>
    </TableHeader>
  </TableRow>
  <TableRow TableRowLevel="1" RowTitle="" TableRowNumber="2" class="OddLegacy">
    <TableCell>
      <Paragraph>ANONYMOUS LOGON</Paragraph>
    </TableCell>
    <TableCell>
      <Paragraph>Group</Paragraph>
    </TableCell>
    <TableCell>
      <UnorderedList UnorderedListLevel="1" class="compactList" UnorderedListNumber="1">
        <ListItem>comment: ANONYMOUS LOGON</ListItem>
        <ListItem>group-id: 7</ListItem>
      </UnorderedList>
    </TableCell>
  </TableRow>
  <TableRow TableRowLevel="1" RowTitle="" TableRowNumber="3" class="Even">
    <TableCell>
      <Paragraph>Administrators</Paragraph>
    </TableCell>
    <TableCell>
      <Paragraph>Group</Paragraph>
    </TableCell>
    <TableCell>
      <UnorderedList UnorderedListLevel="1" class="compactList" UnorderedListNumber="1">
        <ListItem>group-id: 544</ListItem>
      </UnorderedList>
    </TableCell>
  </TableRow>
</Table>

Then my XSLT:

<xsl:variable name="whiteuserxml">
    <item>ANONYMOUS LOGON</item>
</xsl:variable>
<xsl:for-each select="Table">
    <table>
    <xsl:for-each select="TableRow[not(TableCell/Paragraph = $whiteuserxml/item)]">
        <xsl:choose>
        <xsl:when test="count(TableCell) = 0"/>
        <xsl:otherwise>
            <tr>
            <xsl:for-each select="TableHeader">
                <td><b><xsl:apply-templates select="*"/></b></td>
            </xsl:for-each>
            <xsl:for-each select="TableCell">
                        <td><xsl:apply-templates select="*"/></td>
            </xsl:for-each>
               </tr>
        </xsl:otherwise>
        </xsl:choose>
    </xsl:for-each>
    </table>
</xsl:for-each>

Desired output:

<table>
    <tr>
        <td>Administrators</td><td>Group</td><td>the other stufflist</td>
    </tr>
</table>

The problem I'm having is that I can't prevent the table from being created if its going to be empty and by the time I work out whether it contains legitimate rows its too late to add the table name back

Answer 1

you can move that choose up at table level and check if it contains cells

<xsl:when test="count(TableRow/TableCell) = 0"/>

Review: Ok, with the "white list " conditions, still moving the condition up

<xsl:for-each select="Table[count(TableRow[not(TableCell/Paragraph = $whiteuserxml/item)]/TableCell)=0]">...
</xsl:when>

you will have to filter again in the inner loop.

The point is, you can build complex conditions with xslt/xpath that look forward (or other directions) in the data tree. You are not limited to the current node and attributes
