Hi,

I am getting an XML after serializing an object in C#. I need to replace some nodes of the XML programatically. I came to know that it can be done with XSLT. I have never worked with XSLT before and also could not get any relevant information on the internet about it.

Can someone please help me in achieving this.

Below is my XML. I need to replace "Item", "ItemDetail", "Detail" and "Header" tags with some other name.

XML

<rootelement xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<item>
  <itemdetail>
    <itemdetail1>QQQ</itemdetail1>
    <itemdetail2>XYZ</itemdetail2>
  </itemdetail>
</item>
<detail>
  <detail1>DEF</detail1>
  <detail2>ABC</detail2>
</detail>
<Header>
  <Header1>Test </Header1>
</Header>
</rootelement>

Thanks

Why don't you just load the file as text, and do approproriate Replace calls on it:

C#

string myXML = // load the file into this string
myXML = my.XML.Replace("<item>", "<NewItemName>").Replace("</item>", "</NewItemName>");
myXML = my.XML.Replace("<itemdetail>", "<NewItemDetailName>").Replace("</itemdetail>", "</NewItemDetailName>");
myXML = my.XML.Replace("<detail>", "<NewDetailName>").Replace("</detail>", "</NewDetailName>");
myXML = my.XML.Replace("<Header>", "<NewHeaderName>").Replace("</Header>", "</NewHeaderName>");

Of course, one has to wonder why you're doing this. It's completely unneccessary from a programming point of view. The file is what it is.

I still think loading it as text and doing replace based on tag names in a app.config is easier, but with some minor googling, I found this example, and you could have to:

XML

<xsl:template match="item">
   <xsl:element name="NewItemName">
     <xsl:apply-templates select="@*|node()"/>
   </xsl:element>
</xsl:template>

If you want more examples, google is your friend. I searched for "using xslt to change tags" and got back over 700 THOUSAND results.
