QRegExp Usage: How Can I get image names from html string?

Question

html = ... <span>emoticon12</span><img src="qrc:\res\emoticon\emo12.gif" width="20" height="20"/><span>emoticon8</span><div>...</div><img src="qrc:\res\emoticon\emo8.gif" width="20" height="20"/>...<img src="qrc:\res\emoticon\emo9.gif" width="20" height="20"/>...

How can I get all image names as QStringList using QRegExp from html?

result = emo12.gif, emo8.gif, emo9.gif

I can not make regular expression.

You shouldn't use regex to parse HTML: https://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454 — Christian Baumann, Oct 05 '20 at 07:18
This is html but it is treated in QString, not as html(only string). So I think I can use regexp. — Samuel D.Murphy, Oct 05 '20 at 07:23

In this case you could parse them with this pattern: (match is in the first capture group)

(\w+\.\w+)"

Thanks, but there are also .png files. I want only ccc in "/emoticon/ccc.gif" – Samuel D.Murphy Oct 05 '20 at 07:28
