You need subtitles as XML for a system that prefers markup. The SRT to XML Converter wraps each cue in a tidy <cue> element with index, start, end and text fields.
The caption text is XML-escaped so ampersands, angle brackets and quotes never break the document, and the original HH:MM:SS,mmm timing is preserved. The result is well-formed, schema-friendly XML you can validate, transform, or store. Paste your SRT and export.
