Change same tags name into different tags in xml using xslt

Hi All,

Today we will learn about converting same tags of xml can be dynamically change into different tags.

We will see one example here to convert same tags of xml into different tags.

Let’s start with an example:

Input XML:

<books>

<book>

<name>value1</name>

<name>value2</name>

<name>value3</name>

<name>value4</name>

<name>value5</name>

</book>

<book>

<name>value1</name>

<name>value2</name>

<name>value3</name>

<name>value4</name>

<name>value5</name>

</book>

</books>

We can easily see here that if we want to get the value of name tag it won’t be easy. To get the value of name tags from the xml we can easily convert the name tag dynamically using the xslt.

To convert this xml “name” tag we will use XSLT:

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="name">

  <xsl:variable name="ename">

    <xsl:text>column</xsl:text>

    <xsl:number count="name"/>

  </xsl:variable>

  <xsl:element name="{$ename}">

     <xsl:value-of select="."/>

  </xsl:element>

</xsl:template>

When we will use this xslt to xml it will give us this output:

<book>

               <column1>value1</column1>

               <column2>value2</column2>

               <column3>value3</column3>

               <column4>value4</column4>

               <column5>value5</column5>

</book>

<book>

               <column1>value1</column1>

               <column2>value2</column2>

               <column3>value3</column3>

               <column4>value4</column4>

               <column5>value5</column5>

</book>

Please observe that we have changed the name to the column tag and its coming out like column1, column2, column3 … . so now we can easily extract the value of this different tags.
