Only one occurrence of `{static}` is replaced inside a tag

• I have read the Filing Issues and subsequent “How to Get Help” sections of the documentation.

• I can reproduce this problem with stock/default settings file, theme, and sample content (as described in above “How to Get Help” sections of the documentation).

• I have searched the issues (including closed ones) and believe that this is not a duplicate.

Issue

Create a page on a new site that contains a tag with two {static} instructions. For instance an image with lazyloading:

Title: Test Article
Date: 2024-11-02 21:30
Author: me
Category: Uncategorized
Tags: 
Slug: test-article
Status: draft

<img
  src="{static}/images/placeholder.png"
  data-src="{static}/images/my_image.png"
  loading="lazy"/>

Bye

Expected output:

<p><img
  src="/images/placeholder.png"
  data-src="/images/my_image.png"
  loading="lazy"/></p>
<p>Bye</p>

Found output:

<p><img
  src="{static}/images/placeholder.png"
  data-src="/images/my_image.png"
  loading="lazy"/></p>
<p>Bye</p>

The issue comes from the regex

(?P<markup><[^\>]+  # match tag with all url-value attributes
(?:href|src|poster|data|cite|formaction|action|content)\s*=\s*)
(?P<quote>["\'])      # require value to be quoted
(?P<path>[{|](?P<what>.*?)[|}](?P<value>.*?))  # the url value
(?P=quote)"""

that will match only the last attribute (greedy). Changing it to (?P<markup><[^\>]+? makes it lazy and matches the first one only so doesn’t really solves the issue either.

Still trying to find a way to solve this without using 2 regex call but I am no expert in regex. (edit: #3420 maybe?)
