XSLT 1. 0 Grouping by two attributes and creating table

Narendra.Patil · February 26th, 2010, 06:40 AM

Dear Martin,

I have following XML file and I have to create an XSL file for it to genearate the HTML output.

<?xml version="1.0" encoding="utf-8"?>
<SalesChanges xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Country>India</Country>
<State>MP</State>
<City>Indore</City>
<Zip>452369</Zip>
<Created>
<string>Sales Order</string>
<string>Market Research</string>
</Created>
<Updated>
<string>Trends</string>
<string>Costs</string>
<string>Ranges</string>
</Updated>
<Deleted>
<string>Old Product</string>
</Deleted>
</SalesChanges>

Expected output is like

===========================
Country Name : India
State : MP
City : Indore
Zip : 452369

<table border=1>
<tr>
<td>
Created
</td>
<td>
<ul>
<li>Order</li>
<li>Market Research</li>
</ul>
</td>
</tr>
<tr>
<td>
Updated
</td>
<td>
<ul>
<li>Trends</li>
<li>Costs</li>
<li>Ranges</li>
</ul>
</td>
</tr>
<tr>
<td>
Deleted
</td>
<td>
<ul>
<li>Old Product</li>
</ul>
</td>
</tr>
</table>

===========================
Plesae help.

Thanks in advance

Here is a sample XSLT 1.0 stylesheet:

Code:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="1.0">
  
  <xsl:output method="html" indent="yes"/>
  <xsl:strip-space elements="*"/>
  
  <xsl:template match="SalesChanges">
    <xsl:apply-templates select="Country | State | City | Zip"/>
    <table border="1">
      <xsl:apply-templates select="Created | Updated | Deleted"/>
    </table>
  </xsl:template>
  
  <xsl:template match="Country | State | City | Zip">
    <xsl:value-of select="concat(local-name(), ' : ', .)"/>
    <br/>
  </xsl:template>
  
  <xsl:template match="Created | Updated | Deleted">
    <tr>
      <td><xsl:value-of select="local-name()"/></td>
      <td>
        <ul>
          <xsl:apply-templates/>
        </ul>
      </td>
    </tr>
  </xsl:template>
  
  <xsl:template match="string">
    <li><xsl:value-of select="."/></li>
  </xsl:template>

</xsl:stylesheet>

Dear Martin,

If any of the value is blank then table is not well formatted. e.g.
Created and Deleted nodes are blank. Then how to make the table well formatted with border??

<?xml version="1.0" encoding="utf-8"?>
<SalesChanges xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Country>India</Country>
<State>MP</State>
<City>Indore</City>
<Zip>452369</Zip>
<Created />
<Updated>
<string>Trends</string>
<string>Costs</string>
<string>Ranges</string>
</Updated>
<Deleted />
</SalesChanges>

Please help..

If you use

Code:

<table style="emtpy-cells: show;" border="1">...</table>

on your table element, do you get to see the cell borders then? Or which browser(s) do you target?

Dear Martin,

For testing I use IE8 but it is not working for IE8.
Actually I have to tranform the XML to HTML and send it as EmailBody thru application.

Let me know if there is any other option
OR
If there is any way so that I will not show the empty nodes. In our example I will show only Updated node.

Thanks in advance.

Martin Honnen · March 2nd, 2010, 09:41 AM

If you don't want to process the empty nodes then use e.g.

Code:

  <xsl:template match="SalesChanges">
    <xsl:apply-templates select="Country | State | City | Zip"/>
    <table border="1">
      <xsl:apply-templates select="Created[*] | Updated[*] | Deleted[*]"/>
    </table>
  </xsl:template>

to process only those elements having child elements.

I have to create an XSL which give output like

CustomerName R A Msey
Question -
Answer -

Question
Answer

CustomerName D K Bose
Question -
Answer -

Question
Answer

In short I have to join two nodes based on the Cutomer Name in future it might be name and CustomerID two values...

Anyone gone through similar case ...

Thanks in advance

With XSLT 2.0 (as supported by XSLT 2.0 processor like Saxon 9 or AltovaXML) you can do

Code:

<xsl:stylesheet
  version="2.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  
  <xsl:output method="text"/>
  
  <xsl:template match="/">
    <xsl:for-each-group select="//QuestionAnswer" group-by="CustomerName">
      <xsl:text>Customer Name </xsl:text>
      <xsl:value-of select="current-grouping-key()"/>
      <xsl:text>
</xsl:text>
      <xsl:value-of select="current-group()/concat('Question ', QuestionText, '
Answer ', Answer/TextValue)" separator="
"/>
      <xsl:text>
</xsl:text>
    </xsl:for-each-group>
  </xsl:template>
  
</xsl:stylesheet>

With XSLT 1.0 you will need to use Muenchian grouping as document here: http://www.jenitennison.com/xslt/grouping/muenchian.xml

Hello Martin,

Even though the post is not directly related to XSLT; I am putting it here cause I came across one post which was given by...

http://forums.asp.net/t/1428622.aspx/1.

I have two data
1. XML which is coming from the data base and
2. I have created XSLT matching my required output.

I want to process these two a convert into a Word & PDF files (around 80 pages of report).

I came across many third party software to convert XML to PDF but I wish do it through C#. Is there any way that I will be able to use XML and XSL to generate PDF or only way is to use XSL-FO?

Thanks in advance
