In the new release, Burp lets you export full details of interesting requests and responses in XML format, including all relevant metadata such as response length, HTTP status code and MIME type. For example:
If you have annotated any of the exported items, your comments will also be included within the XML.
You can access this feature via the context menu anywhere in Burp that you see requests and responses, and you can include individual items or multiple selections. The raw data and analysis captured within Burp is thereby available for any external tools that can process the XML export.
