How to use the HTML toolbox
HTML Toolbox parses text only in the current browser’s memory; it does not execute scripts, access the network, or save input.
Enter HTML
Paste a HTML fragment and choose tree structure or XPath mode.
Execute parsing
View nodes, attributes, paths, or XPath matching results.
Copy report
Copy the structured tree or matching text after confirming the result.
Limitations and Notes
- The parser does not execute scripts, event handlers, external resources, or custom element behavior.
- XPath only covers restricted XPath 1.0 queries; complex browser extension syntax will be reported as unsupported.
- Enter up to 1 MiB; use at most 100000 nodes; results still need to be verified against the target browser.
