PDF Structure Tree Display and Validation

Upload Tagged PDF

Select a tagged PDF file to upload. Drag and drop the PDF file, or browse using the Browse button.
By default the generated XML will follow any specified Role Mappings so the generated elements should use names from the standard PDF specifications. If the Follow Role Map option is unchecked, the generated elements will use the names and namespaces specified in any locally defined Structure Elements. The LaTeX-Project Structure Elements are declared in the schema used here, but other namespaces result in XML files that will not validate to the supplied schema.
The default Auto schema automatically validates a document against the PDF/UA-1 or PDF/UA-2 schemas extended with LaTeX Namespace elements. You may instead select a specific schema, or None to suppress schema validation.
By default, the generated XML will be displayed by your browser. If you select the Download option, it will be downloaded as document.xml to your default download area.
The returned page will also provide a link to open the Structure Tree in PlantUML syntax at PlantUML.com. This is using a display format produced by the PDF Association. As it is mainly inteded for small fragments of the tree to be included in documentation, this form offers several options to truncate the display, starting at a specific element, or eliding elements under various conditions.

This web version is intended for small illustrative examples only, and is provided as a free service.

We encourage use of a local installation to allow easier experimentation and to reduce load on this server.

show-pdf-tags is a Lua script that just requires the texlua executable that is included in all modern TeX distributions. Source and documentation are on GitHub.
The Relax NG Schema are developed in the same GitHub repository as the Lua script, GitHub.
Any Relax NG validator can be used (RNV and Emacs/nxml are used in development). This web form uses RNV available from davidashen.net.
