RE: [EP-tech] Creators, authors, editors names

CAUTION: This e-mail originated outside the University of Southampton.

Thanks Florian, much appreciated.

I shall check this once I get over a much bigger problem! I have moved to https-only, partly for added security, but also to stop my browser throwing errors because of being served mixed http/https content, that seemed to be at the root of Ajax errors, making certain things unachievable.

However, I have now crunched the site so badly that only the static landing page and few other static pages work. Anything with JS or CSS content has become:

"Not Found

The requested URL was not found on this server.
Apache/2.4.62 (Ubuntu) Server at arcomabstracts.com Port 443"

I am struggling to isolate the problem. I am going on holiday tomorrow, so this may have to wait until I get back!!

Best wishes

Will

Hello Will,

if this is what you have coded ...

>  <epc:item><epc:print ; expr="$name" />
>

... it is not well-formed xml. Put the semi-colon out of the <epc:print>-tag.

Furthermore, the not-equal operator is usually !=, so you could try (I haven't tested it, though) `length(creators_name)!=$index`.
Alternatively you can use <epc:choose><epc:when test="...">....<epc:otherwise>..., I think that is less errorprone.


Best wishes

> If you are changing code, you can always use source code management tools like git, to track all the changes you make, and revert them back if you think you've screwed up. I often use the git flow workflow, and might do a git diff comparison between how the code was before my alterations, and how it is presently, in order to determine if I did mess anything up. Of course, the original of each release is also on github so can be seen in a web browser too, if you want a less command driven approach to spotting the difference and wish to manually browse the originals in a web browser.

> I also recall you can pass the desired template to be used during rendering - so if you are messing about with code, but don't want to mess about with the default template, you can create a template with a custom name, and then call it specifically in your code, passing in the custom template name.
