4.5: Parsing failed: EntityRef: expecting ';'

ajki · 12-10-2019, 07:54 AM

Calibre 4.5, epub, check for errors within epub:

a link is given as in: ... <a href="https://www.xxx.yy/index.php?eID=dumpFile&t=f&f=4182....">...</a>...

note the ampersands in the link

When checking for errors within (the whole) ebook Calibre 4.5 breaks with an error message: "Parsing failed: EntityRef: expecting ';', line xxx, column yyyy..."

Within the editor (edit area and simplified view area) the link itself opens correctly an external browser with the specified page (a pdf in this case). URL encoding (like %26 instead of ampersand) will not display the website.

I think there is something wrong with the regex check within urls

Standalone ampersands are not valid in HTML. You need to use &

*WITHIN* a link? I don't think so....

(and, as implied above, what will a Server answer if it gets "https://..../whatever&whatever..."?)

It will treat the & as a &. And yes, you can use entities in a link. And we are not discussing web links here. You are looking at a link internal to an ebook file which is not governed by the same rules.

I modified the link to this message and Firefox, Chrome and Edge Dev open this link happily:

Or you could url encode your url, as opposed to xml escaping and the & will happily get % encoded.

You (all) are right, I was wrong. Masking with & or %26 actually works without problems - starting the browser from the link within the *preview window* (or from the resulting ebook). My error was Ctrl-clicking on the href-url within the *edit window" (when masking with & or %26. That way the url is given as is within the edit window and the server won't find the page.
