Question

Given this XML

    <ContentBlock>
    <Content>
        <QuickStatus Balance="0" Credits="0" Trolley="600" Delivery="100" Available="-700" Pending="0" />
        <TrolleyItems>
            <TrolleyItem Description="Test Item 1" value="150" />
            <TrolleyItem Description="Test Item 2" value="150" />
            <TrolleyItem Description="Test Item 3" value="300" />
        </TrolleyItems>
    </Content>
</ContentBlock>

I need to check if each of the trolly items value attributes are under 800 and then show the Final delivery attribute if at least one of the items are under 800. But only need to show the Delivery value once.

My XSLT .xsl file code looks like this.

<xsl:for-each select="Content/TrolleyItems/TrolleyItem">
    <xsl:if test="ContentBlock/Content/TrolleyItems/TrolleyItem/@value &lt; 800">
        <tr style="border-bottom: 1px dashed #000;">
            <xsl:for-each select="Content/Final">
            <td>Delivery Fee</td><td><xsl:value-of select="@Delivery"/></td>
            </xsl:for-each>
        </tr>
        </xsl:if>
        </xsl:for-each>

What I need is to output one item for the @Delivery attribute.

It will only show one time for example the answer will be: “Delivery Costs: 100”. So Delivery is only charged when the item value is less than 800

Thanks for the help.

Answer 1

The inner xsl:if and xsl:for-each shouldn’t have the full path.

All nodes within the xsl:for-each are relative to the xpath in the select, and because you’re using relative paths (they don’t start with / or //) then you’re looking for

Content/TrolleyItems/TrolleyItem/ContentBlock/Content/TrolleyItems/TrolleyItem

What I think you’re looking for is something like this…

<xsl:for-each select="Content/TrolleyItems/TrolleyItem[@value">
  <xsl:if test="./@value &lt; 800">
    <tr style="border-bottom: 1px dashed #000;">
      <xsl:for-each select="/Content/Final">
        <td>Delivery Fee</td><td><xsl:value-of select="@Delivery"/></td>
      </xsl:for-each>
    </tr>
  </xsl:if>
</xsl:for-each>

See this xmlplayground for a live demo

Update

Even more efficient…

<xsl:for-each select="Content/TrolleyItems/TrolleyItem[@value &lt; 800]">
  <tr style="border-bottom: 1px dashed #000;">
    <xsl:for-each select="/Content/Final">
      <td>Delivery Fee</td><td><xsl:value-of select="@Delivery"/></td>
    </xsl:for-each>
  </tr>
</xsl:for-each>

Update

Based on the comment by the OP, maybe something more like this (bearing in mind that I assume your actual XML will be a lot more complex that you’re currently showing, so this is probably not exactly what you’re looking for)…

<xsl:if test="Content/TrolleyItems/TrolleyItem/@value &lt; 800">
  <tr style="border-bottom: 1px dashed #000;">
    <td>Delivery Fee</td><td><xsl:value-of select="/Content/Final/@Delivery"/></td>
  </tr>
</xsl:if>
