Conversion of pdf file to text using itext in java Welcome to the Java Programming Forums The professional, friendly Java community. 21,500 members and growing!

Convert HTML to PDF using iText XMLWorker Java Servlet example to generate PDF using iText Creating Table in PDF using Java and iText Generate PDF using Java and iText. Parsing HTML using the default setup is as easy as creating a PDF in five steps: Create a Document object Get a PdfWriter instance. A basic understanding of iText It will result in a bookmark. The first real Element is a Chunk. In the next example, we set the initial leading to 1. Now suppose that this class and method didn't exist. What would we have to do? First you need an instance of the XMLWorker class. With this instance you can create an XMLParser. Finally use its parse() to parse an HTML file. Let's take a look at an example, and examine every step. Real's JAVA JAVASCRIPT WSH and PowerBuilder How-to pages with useful code snippets. Parsing HTML step by step. The following snippet shows what happens in step 4 of the PDF creation process in more detail. We could also have used a Reader object to read the HTML file. XMLParser. The XMLParser class expects an implementation of the XMLParser. Listener interface. XMLWorker is such an implementation. Another implementation (Parser. Listener. Writer) was written for debugging purposes. XMLWorker. The XMLWorker constructor expects two parameters: a Pipeline< ?> and a boolean indicating whether or not the XML should be treated as HTML. If true, all tags will be converted to lowercase and whitespace used to indent the HTML syntax will be ignored. The CSSResolver. Pipeline is responsible for adding the correct CSS Properties to each Tag that is created by XMLWorker. Without a Css. Resolver. Pipeline, the document would be parsed without style. The get. Default. Css. Resolver() method in the XMLWorker. Helper class provides a default Css. Resolver: CSSResolver css. Resolver = XMLWorker. Helper. get. Instance(). Default. Css. Resolver(true). The boolean parameter indicates whether or not the default. XML Worker) should be added to the resolver. Html. Pipeline. Next in line, is the Html. Pipeline. Its constructor expects an Html. Pipeline. Context. Html. Pipeline. Context html. Context = new Html. Pipeline. Context(null). Context. set. Tag. Factory(Tags. get. Html. Tag. Processor. Factory()). Using the set. Tag. Factory() method of the Html. Pipeline. Context, you can configure how the Html. Pipeline should interpret the tags encountered by the parser. We've created a default implementation of the Tag. Processor. Factory interface for parsing HTML. It can be obtained using the get. Html. Tag. Processor. Factory() method in the Tags class. If you want to parse other types of XML, you'll need to implement your own Pipeline implementations, for instance an Svg. Pipeline. Pdf. Writer. Pipeline. This is the end of the pipeline. The Pdf. Writer. Pipeline constructor expects the Document and a Pdf. Writer instance you've created in step 1 and 2 of the PDF creation process. In some cases, using the default configuration won't be sufficient, and you'll need to configure XML Worker yourself. Initially, this class is only aware of the standard Type 1 fonts. Unfortunately, it will be more difficult to find the corresponding bold, italic and bold italic font. Choose your font wisely if you want to avoid this problem. Adding an Image. Provider. If the HTML file you're parsing is stored in a directory that is different from the working directory, i. Text won't be able to create Image objects. The same image bits and bytes will be written to the PDF more than once. You have to implement it yourself, as is done in the following snippet: html. Context. set. Image. Provider(new Abstract. Image. Provider() . If the document is downloaded and consulted off line. If we want the link to work, we need to change the base URL. You can now parse HTML. Now let's take a look at ways to extend XML Worker so that you can also parse other XML documents. Extending the XMLWorker. Depending on the nature of your XML file, you can either write your own Pipeline implementations. Html. Pipeline by adding your own Tag. Processor classes. Let's start by extending the Html. Pipeline. top. How to extend the Html. Pipeline class. We've already configured a Html. Pipeline by changing the Html. Pipeline. Context. You can change these defaults with the following methods: The char. Set() method — change the character set. The set. Page. Size() method — changess the default page size (which is A4)The auto. Bookmark() method — enables or disables the automatic creation of bookmarks. The default is: enabled (true). The set. Accept. Unknown() method — should XML Worker accept unknown tags? The default value is true. The set. Root. Tags() method — by default body and div are set as root tags. This affects the margin calculations. In previous examples, we've also used the set. Tag. Factory() method. Some tags are linked to the Dummy. Tag. Processor (a processor that doesn't do anything), other tags result in a Tag. Processor with a very specific implementation. This will either replace the default functionality of already supported tags. Suppose that you have HTML code in which you've used a custom tag that should trigger a call to a database, for example a < userdata> tag. You should prefer extending Abstract. Tag. Processor. as this class comes with precanned page- break- before, page- break- after, and fontsize handling. Note that your Tag. Processor can use CSS if you introduced a Css. Resolver. Pipeline before each pipeline that wants to apply styles. There's no method to remove a Css. File in the. CSSResolver interface, but that doesn't mean you can't add such a method in your. You can provide inheritance rules for the Style. Attr. Css. Resolver class. Css. Inheritance. Rules() method. By default, the Default. Css. Inheritance. Rules. are used, but you can always write your own implementation of the Css. Inheritance. Rules interface. CSS properties to be inherited from a tag. All of this is very interesting if your XML is very similar to HTML and if your styles are defined using CSS. Creating PDF is only one of the many possible actions. If you need functionality that goes beyond HTML to PDF rendering, you need to implement the Pipeline. This allows you to inherit all the default behavior. In the case of the content(). It contains a list of Writable objects. For instance the Pdf. Writer. Pipeline expects. Process. Object to contain lists of Writable. Elements. This way pipelines can access a Custom. Context of another pipeline. In the existing pipelines this is done in the init. XMLParsers various parse methods. Please consult the source code of the existing pipelines for inspiration when writing your. Pipeline implementation. References. Before you start coding, please consult the requirements to find out if you're using the correct version of i. Text and XML Worker. To implement repeating headers and/or footers, set.
