Example usage

The use of the HTMLGenerator component is quite simple - with only a few lines of code is possible to generate and convert practically any Docx, RTF or Text document to HTML.

Here are some examples of converting the different document types:

Convert Word Docx to HTML from URL to File

This method will convert the Docx to HTML and will save it to given file. The destinationFile parameter is a java.io.File object:

import sferyx.administration.htmlgenerator.*;

HTMLGenerator htmlGenerator=new HTMLGenerator ();
htmlGenerator.generateHTMLFromDocxURL ("http://your_url_here.docx", destinationFile);

or using the file name as String:

import sferyx.administration.htmlGenerator.*;

HTMLGenerator htmlGenerator=new HTMLGenerator ();
htmlGenerator.generateHTMLFromDocxURL ("http://your_url_here.docx", "c:/htmlgenerator-test1.html");

Convert Word Docx to HTML from URL to OutputStream

It will convert the specified Docx document to HTML using the standard page format string such as "A4", "Letter" etc. and and save it to the specified OutputStream. This method will recognize automatically if the document is Docx file and will convert it accordingly. To use this automatic conversion the URL must end with the corresponding extension like docx.

htmlGenerator.generateHTMLFromDocxURL ("http://your_url_here/file.docx", destinationStream);

Convert Rich Text Format RTF to HTML from URL to File

This method will convert the RTF to HTML and will save it to given file. The destinationFile parameter is a java.io.File object:

import sferyx.administration.htmlgenerator.*;

HTMLGenerator htmlGenerator=new HTMLGenerator ();
htmlGenerator.generateHTMLFromRTFURL ("http://your_url_here.rtf", destinationFile);

or using the file name as String:

import sferyx.administration.htmlGenerator.*;

HTMLGenerator htmlGenerator=new HTMLGenerator ();
htmlGenerator.generateHTMLFromRTFURL ("http://your_url_here.rtf", "c:/htmlgenerator-test1.html");

Convert Rich Text Format RTF to HTML from URL to OutputStream

It will convert the specified RTF document to HTML and and save it to the specified OutputStream. To use this automatic conversion the URL must end with the corresponding extension like docx.

htmlGenerator.generateHTMLFromRTFURL ("http://your_url_here/file.rtf", destinationStream);

Convert automatically Word Docx, RTF, Plain Text or Images to HTML using the method generateHTMLFromURL

This method will recognize automatically from the file extension if the document is Docx file, RTF file, Text or images and will convert it accordingly. The output can be saved to java.io.File, java.io.OutputStream etc. To use this automatic conversion the URL must end with the corresponding extension like docx, rtf, txt etc.

htmlGenerator.generateHTMLFromURL ("http://your_url_here/file.docx", "c:/htmlgenerator-test1.html");

Dynamically Generate HTML from Word Docx, RTF, Text and convert multiple files in Java with the Sferyx HTML Generator

You can generate even very complex HTML documents dynamically in your Java application by simply providing all the formatting in HTML and inserting page breaks when new pages are needed - the HTML Generator will take care automatically for all the pagination of long formatted text spanning through multiple pages and also tables, lists etc. This functionality is perfect for creating various reports and other documents which need to be generated dynamically with rich text formatting. You can insert dynamically also Docx files which will be converted automatically to HTML or Rich Text Format, images, Plain Text etc. - everything will be converted automatically and inserted as HTML in the whole document.

import sferyx.administration.htmlgenerator.*;

HTMLGenerator htmlGenerator=new HTMLGenerator();
//Open the content buffer to insert the content - HTML, Docx, RTF, Text etc - everything can be merged together.
htmlGenerator.openContentBuffer();
//Append the content to the content buffer - you can insert styles, images and any kind of formatting.
htmlGenerator.appendHTMLContentToContentBuffer("<style>body{font-size:12pt;color:blue;} h1{background-color:yellow;}</style>");
htmlGenerator.appendHTMLContentToContentBuffer("<h1>This is H1 header</h1>Some other text <b>very important <i>stuff</i></b> with page break after");
//Insert page break to create new page - the HTMLGenerator will handle automatically all the pagination for long text if more pages are needed, tables and everything.
htmlGenerator.addPageBreakToContentBuffer();
//Append the content for the new page.
htmlGenerator.appendHTMLContentToContentBuffer("<h2 style=\"background-color:green;border-bottom:1px solid red;color:white\">This is second H2 header</h2>Some other text <span style=\"color:orange\">extremely interesting <u>stuff</u></b></span><br>");
//Append Plain Text Content
htmlGenerator.appendPlainTextContentToContentBuffer("Here we put some plain text\nin new line other text\n\ttab space other stuff here... with page break after");
//Insert another page break...
htmlGenerator.addPageBreakToContentBuffer();
htmlGenerator.appendHTMLContentToContentBuffer("<style>table{border-collapse:collapse;} td{border:1px solid red;}</style>");
//Create table dynamically...
htmlGenerator.appendHTMLContentToContentBuffer("<table style=\"border:1px solid black;\" ><tr><td>row 1 col 1</td><td>row 1 col 2</td></tr><tr><td style=\"background-color:yellow\">row 2 col 1</td><td>row 2 col 2</td></tr></table> with page break after the table");
//Insert another page break...
htmlGenerator.addPageBreakToContentBuffer();
htmlGenerator.appendHTMLContentToContentBuffer("<h1 style=\"border-bottom:1px solid orange;\">Some other text here and the beginning of the Docx file:</h1>");
....
htmlGenerator.addPageBreakToContentBuffer();
....
//Append MS Word Docx file directly to the content buffer and it will be converted to HTML in the same document
htmlGenerator.appendDocxToContentBuffer(new java.net.URL("file:///c:/test/demo.docx"));
...
//Append Rich Text Format RTF file directly to the content buffer and it will be converted to HTML in the same document
htmlGenerator.appendRTFFileToContentBuffer(new java.net.URL("file:///c:/test/Sample06-1.rtf"));
.....
//Close the content buffer and create the HTML document - there is a possibility to write it to File, OutputStream etc.
htmlGenerator.closeBufferAndGenerateHTML("c:/test/dynamic.html");
