    How to handle Missing Child Element

    I have an XML want and output in HTML so using and XSL for that. The XML file i am using

    <property ref="1">
    <units>
    <unit ref="1">first floor</unit>
    <unit ref="2">second floor</unit>
    <unit ref="3">third floor</unit>
    <unit ref="4">fourth floor</unit>
    </units>
    <leases>
    <lease ref="1">OPEN</lease>
    <lease ref="2">CLOSE</lease>
    <lease ref="3">OPEN</lease>
    </leases>
    </property>

    I want to find out the HTML output where the property unit compared with lease. Facing problem when unit ref="4" but dont find out lease with same ref so want a text against that

      Not entirely sure what you're doing

      [code=xml]
      <xsl:template match="unit">
      <tr>
      <td><xsl:valu e-of select="."/></td>
      <xsl:variable name="lease">
      <xsl:choose>
      <xsl:when test="//lease[@ref = current()/@ref]"/>
      <xsl:value-of select="//lease[@ref = current()/@ref]"/>
      </xsl:when>
      <xsl:otherwise> not found</xsl:otherwise>
      </xsl:choose>
      </xsl:variable>
      <td><xsl:valu e-of select="$lease"/></td>
      </tr>
      </xsl:template>
      [/code]

                  I want to remove last line

                  You have helped me with removing the last line, thanks for the help.

                  Now my requirement has changed bit further.

                  Presently my O/p is as below:

                  first floor OPEN
                  second floor CLOSE
                  third floor OPEN
                  fourth floor not found

                  Now I want to show O/p:

                  first floor OPEN

                  with
                  Prev. & Next Button
                  On click of them will move to

                  second floor CLOSE

                  with
                  Prev. & Next Button
                  On click of them will move to

                  third floor OPEN

                  Simillarly till the last record.

                      I can't understand ur problem clearly. But try like this

                      <xsl:if text="unit[@ref]">
                      <xsl:value-of select="@ref"/>
                      </xsl:if>

                      <xsl:if text="lease[@ref]">
                      <xsl:value-of select="@ref"/>
                      </xsl:if>

                      -----------------------------------------------------------------------------------------------------
