Pdf to xml pdfextractor stack overflow3/17/2023 Since XML is made mainly for text data, you will have to deal with graphics somehow if you want to store in XML, e.g. You will have to take care of newpage, newline, page number, headers, images, graphics, tables, and many more by yourself. If you are really determine to do it, I suggest you use a library to read PDF into objects, and start writing a converter from there. Since each PDF document is very much different, it is almost impossible to automate this without human aids. In order to convert from a format which does not have semantic to a format which have implicit you will need to add your own logic into the conversion process otherwise you will just end up having a mess in your XML which contradicts the whole purpose of using XML. This means it contains implicit semantic. On the other hand, XML is desinged to store text data in a well structured manner. You will not be able to extract the semantic of it easily. There are libraries which allow you to manipulate PDF objects in PDF document but it will not be able to tell you whether an image is related to which paragraph. It is designed for rendering 2D graphics and text documents. Examples can be found at f1040ezt.pdf file under test/data folder.PDF is one of the worst format to work with. Current implementation for buttons only supports "link button": when clicked, it'll launch a URL specified in button properties. Interactive forms can be created and edited in Acrobat Pro for AcroForm, or in LiveCycle Designer ES for XFA forms. V0.1.5 added interactive forms element parsing, including text input, radio button, check box, link button and drop down list. "OCR B MT,Courier New,Courier,monospace" // 05 - OCR-B MT - OCR readable san-serif fixed font "OCR-A,Courier New,Courier,monospace", // 04 - OCR-A - OCR readable san-serif fixed font "QuickType Mono,Courier New,Courier,monospace", // 03 - QuickType Mono - san-serif fixed font "QuickType Condensed,Arial Narrow,Arial,Helvetica,sans-serif", // 01 - QuickType Condensed - thin sans-serif variable font "QuickType,Arial,Helvetica,sans-serif", // 00 - QuickType - sans-serif variable font It does require the client of the payload to have the same dictionary definition to make sense out of it when render the parser output on to screen. This dictionary data contract design will allow the output just reference a dictionary key, rather than the actual full definition of color or font style. Same reason to having "HLines" and "VLines" array in 'Page' object, color and style dictionary will help to reduce the size of payload when transporting the parsing object over the wire. pdf2json will always try load field attributes xml file based on file name convention (pdfFileName.pdf's field XML file must be named pdfFileName_fieldInfo.xml in the same directory). V0.4.5 added support when fields attributes information is defined in external xml file. 'TS': fontFaceId, fontSize, 1/0 for bold, 1/0 for italic.More info about 'Style Dictionary' can be found at 'Dictionary Reference' section 'S': style index from style dictionary.'R': an array of text run, each text run object has two main fields:.If a color can be found in color dictionary, 'oc' field will be added to the field as 'original color" value. 'clr': a color index in color dictionary, same 'clr' field as in 'Fill' object.'x' and 'y': relative coordinates for positioning.'Texts': an array of text blocks with position, actual text and styling information:.More info about 'color dictionary' can be found at 'Dictionary Reference' section. 'Fills': an array of rectangular area with solid color fills, same as lines, each 'fill' object has 'x', 'y' in relative coordinates for positioning, 'w' and 'h' for width and height in page unit, plus 'clr' to reference a color with index in color dictionary.PdfParser.on("pdfParser_dataReady", pdfData => is added to line object PdfParser.on("pdfParser_dataError", errData => console.error(errData.parserError) ) Parse a PDF file then write to a JSON file:.You can convert all kinds of documents and images to PDF files or convert PDF files to DOC, DOCX, XLS, XLSX, PPT, PPTX, XML, CSV, ODT, ODS, ODP, HTML, TXT. More details can be found at the bottom of this document. Click the 'Choose Files' button to select multiple files on your computer or click the dropdown button to choose an online file from URL, Google Drive or Dropbox.To Run in RESTful Web Service or as Commandline Utility The goal is to enable server side PDF parsing with interactive form elements when wrapped in web service, and also enable parsing local PDF to json file when using as a command line utility. Pdf2json is a node.js module that parses and converts PDF from binary to json format, it's built with pdf.js and extends it with interactive form elements and text content parsing outside browser.
