Is regex available in Sigil clip editor?

[mavaddat]

I see that the Sigil Clip Editor has some basic regex (e.g., the first numbered group

\1

matches the entire selected text in the replace text and

\U

recalls the text with the entire selected text in uppercase), but I don't see any specification of the syntax for the Clip Editor. Does anyone know what the full range of regex available to the Clip Editor?
Specifically, I am wondering if I can easily parse the selected text using regex pattern and replace it with some other text using the Clips functionality.

Sigil uses a PCRE engine. You should be able to use most standard PCRE operators.

Sigil uses PCRE engine for regular expressions.

Yes, you can use parentheses () to capture.

Search: ([abc]+)([def]+)([hij]+)
Replace: \1\2\3

Each Regex within the parentheses becomes its own "group", which you can then replace using \1, \2, \3, [...].

\U tells regex to "uppercase everything beyond this point". So let's say you only wanted to uppercase the groups 2 and 3:

Search: ([abc]+)([def]+)([hij]+)
Replace: \1\U\2\3

Side Note: See "Use Parentheses for Grouping and Capturing" on Regular-Expressions.info and "Numbered Backreferences" for more information.

Thank you both for your assistance.
I am specifically interested in constructing a Sigil Clip that is able to manipulate selected text according to a pre-defined pattern.
However, I am not sure where I am supposed to put the pattern that I am anticipating when using Clip function.
I know how to do this regex using find/replace, but not with Clip. Where do I specify the find pattern?

You can't use find patterns with clips.

You might be mixing up Clips with Saved Searches (Tools > Saved Searches).

The way that Sigil Clips works is you highlight text, and then you apply the Clip.

Your highlighted text will be grouped into:

\1

So let's say you highlight:

This is text I |want in italics|.

Clip: <i>\1</i>

This is text I <i>want in italics</i>.

Clips are designed more as a one-button-push for redundant stuff (like pasting in template code for a figure with caption, etc. etc.)

Like I created this Sigil Clip for myself:

<div class="chart">
      <div class="single-chart">
        <div class="chart-title"></div>

        <div class="image"></div>

        <div class="chart-caption"></div>
      </div>
</div>

and then I can easily just insert the needed info/images.

To do more advanced Search/Replace using Regex, you use Tools > Saved Searches.

But you can replace selected (highlighted) text with a clip.
Here is what I use to uppercase a selection
\U\1\E

There also is an "Uppercase" button in the toolbar.

Thanks all! Tex2002ans and Doitsu's responses answer the question for me.
