Merge HTML Template Java

In modern web development, the separation of content and presentation is a fundamental principle. HTML templates provide a convenient way to define the structure and layout of web pages, while JSON and XML data formats are commonly used to store and transmit structured information. Combining these technologies allows developers to dynamically generate HTML content based on data from external sources. In this blog post, we will explore how to merge HTML templates with JSON or XML data in Java.

Merge HTML Template with XML Data in Java

XML (eXtensible Markup Language) is a widely used data format that represents structured data in a hierarchical manner. You can merge the HTML template with XML data in Java by following the steps below:

  1. Load the HTML template and the XML format data.
  2. Merge the HTML template with XML data with the ConvertTemplate method.

The code snippet below demonstrates how to merge an HTML template with XML data in Java:

// HTML template document 
HTMLDocument templateHtml = new HTMLDocument("HTMLTemplateforXML.html");

// XML data for merging 
TemplateData data = new TemplateData("XMLTemplate.xml");

// Output file path 
String templateOutput = "HTMLTemplate_Output.html";

// Merge HTML tempate with XML data
Converter.convertTemplate(templateHtml, data, new TemplateLoadOptions(), templateOutput);

Merge HTML Template with JSON Data in Java

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is widely used for representing structured data. You need to follow the steps below to merge the HTML template with JSON data in Java:

  1. Create an object of HTMLDocument class to load the source HTML template.
  2. Merge the HTML template with the JSON data.

The following sample code shows how to merge an HTML template with JSON data in Java:

// HTML template document 
HTMLDocument templateHtml = new HTMLDocument("HTMLTemplateForJson.html");

// JSON data for merging 
TemplateData data = new TemplateData("JsonTemplate.json");

// Output file path 
String templateOutput = "MergeHTMLWithJson_Output.html";

// Merge HTML tempate with JSON data
Converter.convertTemplate(templateHtml, data, new TemplateLoadOptions(), templateOutput);
