Create a Hello World PDF document through XML and API

In the previous sessions of this Programmer's Guide Reference, we have seen that it is possible to produce a PDF document from a simple XML file. In that case, all the content stored in the XML file is converted to a PDF document. But sometimes, a programmer may require to import the content from an XML file and then control the XML content at runtime before converting into PDF document.

 

This feature can be achieved by combining the XML and Aspose.Pdf simple API.

 

Note: The input XML file must follow the Aspose.Pdf Schema .

 

Please follow these steps to create a PDF document using the combination of an XML file and Aspose.Pdf API:

 

• Create an instance of Pdf class that represents a PDF document
• If you have purchased a license then you should also embed the code to use that license with the help of License class in Aspose.Pdf namespace
• Bind the input XML file to the instance of Pdf class by calling its BindXML method
• Add or change the content dynamically. For example, the content of a Text Paragraph in a Section can be changed using API
• Save the bound XML with Pdf instance as a PDF document

 

Code Snippet

 

[Input XML File]

 

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

  <Pdf xmlns="Aspose.Pdf">

   <Section>

            <Text ID="Text1"> </Text>

   </Section>

  </Pdf>

 

[C#]

 

//Create pdf document

Pdf pdf1 = new Pdf();

 

//Instantiate License class and call its SetLicense method to use the license

Aspose.Pdf.License license = new Aspose.Pdf.License();

license.SetLicense("Aspose.Pdf.lic");

 

//Bind XML into the document

pdf1.BindXML("../../../Example-XML/HelloWorld.XML",null);

 

//Get the first Section from the PDF document

Section sec1 = pdf1.Sections[0];

 

//Get the Text paragraph (whose ID is Text1) from the section

Text text1 = sec1.Paragraphs["Text1"] as Text;

 

//Add a text Segment to the text paragraph

text1.Segments.Add("Hello World");

 

//Save the document

pdf1.Save("HelloWorld.pdf");

 

[VB.NET]

 

'Create pdf document

Dim pdf1 As Pdf = New Pdf()

 

'Instantiate License class and call its SetLicense method to use the license

Dim license As license = New license

License.SetLicense("Aspose.Pdf.lic")

 

'Bind XML into the document

pdf1.BindXML("../../Example-XML/HelloWorld.XML", Nothing)

 

'Get the first Section from the PDF document

Dim sec1 As Section = pdf1.Sections(0)

 

'Get the Text paragraph (whose ID is Text1) from the section

Dim text1 As Text = sec1.Paragraphs("Text1")

 

'Add a text Segment to the text paragraph

text1.Segments.Add("Hello World")

 

'Save the document

pdf1.Save("HelloWorld.pdf")
