I Have a XML file like this

<Tester author="Name" id="16384543">
  <insert tableName="sampletable">
    <column name="id" valueNumeric="2"/>
    <column name="name" value="kathy"/>
    <column name="active" valueBoolean="true"/>
    <column name="age" valueNumeric="2"/>
  </insert>
  <insert tableName="sampletable">
    <column name="id" valueNumeric="23"/>
    <column name="name" value="Queen"/>
    <column name="active" valueBoolean="true"/>
    <column name="age" valueNumeric="29"/>
  </insert>
  <insert tableName="sampletable">
    <column name="id" valueNumeric="25"/>
    <column name="name" value="varshan"/>
    <column name="active" valueBoolean="false"/>
    <column name="age" valueNumeric="5"/>
  </insert>
</Tester>

I need to convert the XML into CSV like below:

id,name,active,age
2,kathy,TRUE,2
23,Queen,TRUE,29
25,varshan,FALSE,5

Requriement:

These column attributes will be dynamic and it will be different for different XMLs. Can someone help?

Here's a way this could be done.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    version="1.0">

  <xsl:output method="text"/>

  <xsl:template match="/">
    <!-- Header -->
    <xsl:apply-templates select="Tester/insert[1]">
      <xsl:with-param name="header">true</xsl:with-param>
    </xsl:apply-templates>
    <!-- Data -->
    <xsl:apply-templates select="Tester/insert"/>
  </xsl:template>
  
  <xsl:template match="insert">
    <xsl:param name="header"/>
    <xsl:for-each select="column">
      <!-- For the header take the name attribute, else take the attribute starting with value -->
      <xsl:choose>
        <xsl:when test="$header='true'">
          <xsl:value-of select="@name"/>
        </xsl:when>
        <xsl:otherwise>
          <xsl:value-of select="@*[starts-with(name(),'value')]"/>
        </xsl:otherwise>
      </xsl:choose>
      <!-- Insert comma between values, except for last value insert new line -->
      <xsl:choose>
        <xsl:when test="position()=last()">
          <xsl:text>&#xa;</xsl:text>
        </xsl:when>
        <xsl:otherwise>
          <xsl:text>,</xsl:text>
        </xsl:otherwise>
      </xsl:choose>
    </xsl:for-each>
  </xsl:template>
  
</xsl:stylesheet>
