Merge Xml Files in PDF Document & Reduce Code Duplication

Published: 15 Mar 2011 By Sher Azam

This technical tip shows how to merge Xml Files in PDF Document. Sometimes different PDF documents share some same content. For example, a number of PDF documents may have the same header or footer. In such cases, a lot of code duplication might be experienced by developers. To reduce this code duplication, it's a good practice to save the content (shared by multiple PDF documents) into different XML files and then merge the XML files together before generating PDF documents.

Example: .Net Framework 2.0 and VS 2005

[C#] 
 
FileStream fs1 = new FileStream(@"D:\AsposeTest\Example.xml", FileMode.Open);
FileStream fs2 = new FileStream(@"D:\AsposeTest\Example.xslt", FileMode.Open);
 
Pdf pdf1 = new Pdf();
 
pdf1.BindXML(fs1, fs2);
 
pdf1.Save("D:/Asposetest/XMlXSLTMERGE.pdf");
 
fs1.Close();
fs2.Close();

Example: .Net Framework 1.1 and VS 2003

[C#] 
 
XmlDocument xmlDoc = new XmlDocument();
MemoryStream ms = new MemoryStream(); 
 
XslTransform xsl = new XslTransform(); 
xsl.Load("test.xslt"); 
xsl.Transform(xmlDoc,null,ms); 
 
ms.Position = 0; 
xmlDoc.Load(ms); 
ms.Close(); 
 
Pdf pdf = new Pdf(); 
pdf.BindXML(xmlDoc,null); 
 
pdf.Save("e:/temp/test.pdf");

[VB.NET] 
 
Dim xmlDoc As XmlDocument = New XmlDocument()
Dim ms As MemoryStream = New MemoryStream()
 
Dim xsl As XslTransform = New XslTransform()
xsl.Load("test.xslt")
xsl.Transform(xmlDoc, Nothing, ms)
 
ms.Position = 0
xmlDoc.Load(ms)
ms.Close()
 
Dim pdf As Pdf = New Pdf()
pdf.BindXML(xmlDoc, Nothing)
 
pdf.Save("e:/temp/test.pdf")

[test.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="/"> 
       <Pdf xmlns="Aspose.Pdf"> 
         <Section> 
                 <Header> 
                         <xsl:copy-of select="document('header.xml')"/> 
                 </Header> 
                 <xsl:copy-of select="document('content.xml')"/> 
         </Section> 
       </Pdf> 
   </xsl:template> 
</xsl:stylesheet>

[header.xml] 
 
<Text> 
        <Segment>header</Segment> 
</Text> 
 
[content.xml] 
 
<Text> 
         <Segment>Hello world</Segment> 
</Text>
