AccuRev's merge algorithm treats HTML-format files just like all other text files: merging takes place line-by-line; no attempt is made to parse the files' HTML data structures in determining difference sections.
At any time, you can click the
Show HTML Result button at the right side of the toolbar. (This button appears only when you're merging a file with a
.htm or
.html suffix.)
Clicking the Show HTML Result button displays a rendering of the merged HTML-format text in the upper pane. This button is a toggle: click it again when you're finished viewing the rendered HTML code and you want to return to performing the merge.
