converting eBooks@Adelaide to mobi

[ericshliao]

I wanted to convert some epub of eBooks@Adelaide to mobi. The conversion is ok with only one problem. It seems that every horizontal rule in epub is converted to page-break in mobi. It's not my desired result. I guess the problem can be fixed by setting proper parameters in conversion config of calibre, such as in "Search & Replace". I tried to study how to do it but couldn't find a solution. EBooks@Adelaide uses css, instead of common <HR> tag. Since I am not familiar with css, I must ask for some help.
Please share a way to set proper parameter. Any help is appreciated.

For now, I can remove undesired page-break by adding the following regex in calibre.

(?is)<div class="dochead">.*?</div>
(?is)<div class="navigation">.*?</div>
(?is)<div class="docinfo">.*?</div>

I don't think it a perfect workaround because these regex will remove page-break and a set of <div></div>. Even though they are not relevant, I still want to ONLY remove page-break.
