html vs xhtml

[cybmole]

I have some confusion over these files types & over how Sigil inserets splits...

It may be used an issue with one bad book - which is a short story compilation that I think has been converted from word but anyway...


inspecting several epubs I have these questions:

1. I see that some have html fiels per chapter, some have xhtml files - I see no obvious rules as to which is uses - is that publisher discretion or a side effect of wahtever package was used to create the book. are both equally valid.

2, if I take a book which is all xhtml and arbitrarily add a split - the new file is also xhtml. if the book was all html, then so is the new file. All very logical

3. But in my problem case I see to have a mix of both types & I don't know if that is ancient editing by me, with an old version of sigil, or not ?

so can someone please tell me has sigil always worked the same way when splitting, and are there any real life consequences ( say in different readers) of changing or mixing the html *& xhtml files types within the epub zip, please

PS this relates to a query I just put on Kobo forum that I am trying to puzzle out - not sure yet if it is a sigil issue a kobo issue, or a waste of time

All files are XHTML internally. It is only the extension that can be either .xhtml or .html. There was a change around 0.6.x with regards to the default extension. In essence it will not matter what the extension is.

OK - so whatever obscure epub bug I am trying to trace, it won't be connected to whatever a component file or files is/are called html or xhtml.

That's good I think, One less suspect on the list

and sigil has always used the source file type, when asked to insert a split into a file via the toolbar icon it woud never split , say , sample.xhtml into

sample.xhtml
sample_Section_1.html

if I'm seeing that then some other program has been at work ?

Or other version of Sigil.

ah - So this could be my own dabbling from when I had sigil v4 - The book has been lying around unread for 2+ years, I may have done a partial tidy /split, then abandoned it.

Also, I was very slow to upgrade from v4.

I am having a sort through old, unread books in my calibre library this one just earned its place in the "bin" pile

I'm finally accepting that if if it's been there for 2+ years & I've still not read it , & its not part of a favourite author or series collection, then it ain't ever going to happen !
