Adding element in middle of xml using xslt

问题:

Below is the actual xml:

<?xml version="1.0" encoding="utf-8"?>
<employee>
 <Name>ABC</Name>
 <Dept>CS</Dept>
 <Designation>sse</Designation>
</employee>

And i want the output as below:

<?xml version="1.0" encoding="utf-8"?>
<employee>
 <Name>ABC</Name>
  <Age>34</Age>
 <Dept>CS</Dept>
  <Domain>Insurance</Domain>
 <Designation>sse</Designation>
</employee>

Is this possible to add XML element in between using xslt? Please give me sample!

Here is an XSLT 1.0 stylesheet that will do what you asked:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
   <!-- Identity transform -->
   <xsl:template match="@* | node()">
      <xsl:copy>
         <xsl:apply-templates select="@* | node()"/>
      </xsl:copy>
   </xsl:template>

   <xsl:template match="Name">
      <xsl:copy-of select="."/>
      <Age>34</Age>
   </xsl:template>

   <xsl:template match="Dept">
      <xsl:copy-of select="."/>
      <Domain>Insurance</Domain>
   </xsl:template>
</xsl:stylesheet>

Obviously the logic will vary depending on where you will be getting the new data from, and where it needs to go. The above stylesheet merely inserts an <Age> element after every <Name> element, and a <Domain> element after every <Dept> element.

(Limitation: if your document could have <Name> or <Dept> elements within other <Name> or <Dept> elements, only the outermost ones will have this special processing. I don't think you intend for your document to have this kind of recursive structure, so it wouldn't affect you, but it's worth mentioning just in case.)

I have modified few things in the existing stylesheet ,it will allow you to choose the specific element and update in your xml.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
   <!-- Identity transform -->
   <xsl:template match="@* | node()">
      <xsl:copy>
         <xsl:apply-templates select="@* | node()"/>
      </xsl:copy>
   </xsl:template>

   <xsl:template match="Name[1]">
      <xsl:copy-of select="."/>
      <Age>34</Age>
   </xsl:template>

   <xsl:template match="Dept[1]">
      <xsl:copy-of select="."/>
      <Domain>Insurance</Domain>
   </xsl:template>
</xsl:stylesheet>

XML:

<?xml version="1.0" encoding="utf-8"?>
<employee>
 <Name>ABC</Name>
 <Dept>CS</Dept>
 <Designation>sse</Designation>
 <Name>CDE</Name>
 <Dept>CSE</Dept>
 <Designation>sses</Designation>
</employee>
