Description

I am trying to convert documents to HTML, then looking through the HTML for anchor tags to find links to external URLs. This works fine when looking at some document types, including PDFs, Open Document formats, Microsoft Word formats .doc and .docx, and the older Microsoft Excel .xls format, but it does not work for any Microsoft Powerpoint formats (.ppt or .pptx) and it does not work for the newer Excel .xlsx format. For the .ppt, .pptx, and .xlsx formats, the text is extracted properly and formatted into HTML, but the link is not converted to an anchor tag.

I am running tika in --server --html mode.

I included samples of .xlsx, .ppt, and .pptx files that do not properly extract links, and also included samples of .ods and .odp files that do extract links properly.
