How to convert ''Headings'' to ''HEADINGS''?

[chaot]

Yesterday you helped me to solve a remotely similar issue! But try&error (with superficial knowledge) isn't the right approach to something serious like that, I think!

How to convert 'fully wrapped' headings to upper case? Please consider the richness of German: that is the existence of äöüß (apart from »«!? plus digits).

<h3 id="uoiDbz7uDaeECwRVEqYwYE5"><a href="Inhalt.html#Die 9 »weißen« Städte!">Die 9 »weißen« Städte!»</a></h3>

Wanted result: <h3...>DIE 9 »WEIßEN« STÄDTE!</a></h3>

Using the predefined function (in the editor of Calibre): Upper-case text (ignore tags)

Search:
<h3.+</h3>

[Turtle91]

try a search and replace:
search:<h3(.*?)><a(.*?)>(.*?)</a></h3>
replace:<h3\1><a\2>\U\3\E</a></h3>

You can also do this via css without changing the actual xhtml:

h3 { text-transform: uppercase; }

Unfortunately text-transform does not work with Adobe RMSDK, the most extended render for epubs.

(with Regex-Function) Unfortunately → Find marks & Replace deletes the whole heading.

@jhowell & @ jbacelar: The non-rendering of text-transform I experienced already practically & unpleasantly enough. Therefore I look now for other solutions.

Issues removed

Off topic!

With your sample code:

<h3 id="uCmGQHCT4I2zAoOwD2nYQT3"><a href="Inhalt.html#Immer seltener werden in dieser Welt ... (undat.)>Immer seltener werden in dieser Welt ...</a></h3>

Search:
<h3.+</h3>
And Regex-Function: Upper-case text (ignore tags)

I get:

<h3 id="uCmGQHCT4I2zAoOwD2nYQT3"><a href="Inhalt.html#Immer seltener werden in dieser Welt ... (undat.)>IMMER SELTENER WERDEN IN DIESER WELT ...</a></h3>

Funny! Here not. As I described: Find marks & Replace deletes the whole heading.

Turtle91's regex does work, but only with PCRE-enabled editors such as Sigil. (Calibre uses the Python regex engine which is not PCRE compatible.)

With Turtle91's regex expressions you'll end up with the following in Sigil:

<h3 id="uoiDbz7uDaeECwRVEqYwYE5"><a href="Inhalt.html#Die 9 »weißen« Städte!">DIE 9 »WEISSEN« STÄDTE!»</a></h3>

As you can see, the PCRE engine is smart enough to replace the ß ligature with SS, which is probably what you want.

BTW, your fragment URL (Inhalt.html#Die 9 »weißen« Städte!) is invalid because it contains spaces and non-ASCII characters.

... weissen ... is the original spelling. I manipulated the example ''for every eventuality''.

I will not do that again. It's silly!

Yes, you are right: now I recognize it. I didn't test and what you found faulty is just a by-product of my manipulation.

OK! I will now try to load the book in sigil to let the capitalisation done there.

Does your search box have the same settings as the image?

[chaot]

@Doitsu Quick and easy! My first attempt ever (or seriosly nearly ever) to sigil. I got it.

@Turtle91 regex (#3) functions (in sigil).

@jbacelar Sorry! That ... weisse Städte ... example doesn't exist anymore. It's already configured.
Please let me give you two ''real'' examples (which doesn't function → as described in #6).

Luck and to the bull!

Exactly the same!
