About fdf/xfdf/xml
Foxit PDF SDK, as an outstanding document processing tool, offers users abundant functionalities and high flexibility. Among them, the FDF, XFDF, and XML file formats play crucial roles in PDF processing. This article will provide you with a detailed introduction to these file formats, their definitions, uses, and their utilization within the Foxit SDK.

What is the FDF file?
FDF (Forms Data Format) is a file format used for processing interactive form data. It is responsible for storing form data, annotations, and page layout information within a PDF document. FDF can be used to submit form data to servers, receive responses, and integrate them into interactive forms. Additionally, FDF supports exporting form data as standalone files, facilitating storage, transmission, and reimporting into corresponding PDF interactive forms. Moreover, FDF files can define annotation containers, separating them from applicable PDF documents, enabling flexible annotation management.
What is the XFDF file?
XFDF (XML Forms Data Format) is an XML-based version of FDF with similar functionalities. It stores form data and annotations in XML format, offering higher readability and ease of handling. XFDF files can be easily exported and imported to manage form data storage and sharing conveniently. XFDF maintains compatibility with FDF, allowing data exchange in different environments, thus providing greater flexibility for form data processing.
What is the XML file?
XML (eXtensible Markup Language) is a universal markup language used for representing structured data. In the context of the Foxit PDF SDK, XML files are commonly used to describe the structure, content, and attributes of PDF documents. Through XML files, users can extensively configure and customize PDF documents to fulfill personalized document processing needs. The XML format enables users to define elements such as page layout, bookmarks, links, annotations, styles, and more, enabling comprehensive document customization.
Applications of FDF, XFDF, and XML
● FDF
- Dedicated to Form Data: The FDF file format is specifically designed for processing interactive form data, efficiently handling submission, integration, and storage of form data.
- Annotation Container Support: FDF files allow defining annotation containers, separating annotations from PDF documents for more flexible annotation management.
- User-Friendly: The FDF file format is relatively simple, making it easy to create, edit, and process, facilitating convenient data exchange and integration.
● XFDF
- Based on XML Markup: XFDF files use XML markup language, providing higher readability and intuitive handling for data exchange.
- Structured Data Exchange: XFDF files support rich data structuring, facilitating data import, export, and sharing.
- Flexibility and Compatibility: Building upon the FDF format, XFDF maintains a level of compatibility, enabling exchange across different environments, and also allows user-defined markup for personalized data descriptions.
● XML
- Versatility: XML file format is a universal markup language applicable for describing various types of data, serving a wide range of application domains.
- Structured Representation: XML files support highly structured data descriptions, enabling definition of complex document elements, attributes, and relationships to meet diverse processing needs.
- Extensibility: Users can easily extend XML file markup to achieve specific application scenarios, satisfying customized requirements.
In conclusion, FDF, XFDF, and XML file formats each possess unique advantages in document processing. Developers can choose the most suitable format based on their actual needs to achieve optimal results in data exchange, storage, and customization. Foxit PDF SDK provides robust support for these file formats, empowering developers to better address document processing challenges.
Application of FDF/XFDF/XML in Foxit PDF SDK
Foxit PDF SDK offers support for the FDF file format, making interactive form data processing simple and efficient:
● Form Data Interaction: With Foxit SDK, you can easily create, read, and edit FDF files, achieving form data interaction and integration.
For example: Import form fields and annotations from an FDF/XFDF document.
This allows importing fields and annotations into a PDF document, as shown in the illustration:
Additionally, you can also load FDF/XFDF files using streams:
It also supports importing form fields in FDF template. The page associated with the FDF template will be inserted into the end of the document.
For more details, refer to the article: https://developers.foxit.com/developer-hub/document/how-to-import-a-template-based-fdf-to-pdf/.
● Import and Export: Foxit SDK allows you to associate FDF files with PDF documents, enabling data import and export. You can export form data as FDF files for convenient storage, transmission, and backup, and subsequently reapply the data to the corresponding PDF forms through import operations.
For example:Export form fields and annotations to a FDF/XFDF document：
Export the form data to an XML file：
Import the form data from an XML file：
In addition, importing and exporting XML files to form fields also support streaming methods.
File Structure of FDF/XFDF/XML
● FDF File Structure
- Header: An FDF file begins with a header, usually containing version information and encoding indications. This section defines the FDF file’s format version and the character encoding used.
- Start and End: FDF files use specific markers to indicate their start and end. The start marker is typically %FDF-1.2, indicating the FDF file’s version. The end marker is %%EOF, indicating the file’s end.
- Dictionary Objects: FDF files contain one or more dictionary objects describing form fields and annotations. Each dictionary object is enclosed in angle brackets << and >> and contains a series of key-value pairs. These pairs define the field’s name, value, type, and other properties. For instance, a form field’s dictionary object might contain key-value pairs like /T (Field Name), /V (Field Value), /FT (Field Type), etc.
- Annotation Descriptions: In FDF files, annotation descriptions define information related to annotations within the PDF document, such as annotation type, position, color, etc. These descriptions appear in the form of dictionary objects and can contain multiple key-value pairs to describe various annotation attributes.
- Link Information: FDF files can also contain information related to links for creating and managing links within the PDF document.
- Other Information: FDF files can include other information relevant to PDF document interaction and processing, such as form submission addresses, data export methods, etc.
For example, a typical FDF format might look like:
● XFDF File Structure:
- Root Element: The root element of an XFDF file is typically <xfdf>.
- Field Data: Each form field in the form is represented by one or more <field> elements, containing the field’s name (<fieldname>) and value (<value>).
- Annotation Data: If the PDF file contains annotations such as comments or highlights, they can be represented using the <annots> element.
- Page Data: Data can be associated with specific PDF pages using the <page> element.
- Additional Data: XFDF files can also include other data related to PDF forms.
● XML File Structure:
- Tags and Elements: XML files use tags and elements to represent data. Tags are enclosed in angle brackets, and elements consist of tags, attributes, and text content.
- Hierarchy: Elements in an XML file can be nested, creating a hierarchical structure. Parent elements can contain child elements, forming relationships between data.
- Attributes: Elements can have attributes, providing key-value pairs with additional information about the element.
- Text Content: Elements can contain text content, representing the actual data.
- Comments: XML files can include comments for explanatory and descriptive purposes.
