Extract h2 and h3 from database
Hello and bravo for the new Texpattern 4.7.3 :)
I’d like to build an oveview of all the articles I’ve written in my website.
I am wondering how I could extract directly form the Body field in the textpattern table in the DB all the h2. and h3.
Since there is not REGEXP_SUBSTR function in MySQL, what would be the best way to do it, as a MySQL query, or any other way.
The answer my be in the depths of this forum… I confess that did very little search ?♀️

FWIW, there is REGEXP_SUBSTR in MySQL 8, but it returns only one match.

- I need all the occurences
- My provider runs an older version
I looked at etc_query but can’t figure out if this would be a good use.

Ah, if you are not limited to MySQL, this should do:
<txp:article_custom>
<txp:etc_query data='<txp:body />' query="//h2|//h3" />
</txp:article_custom>It extracts textiled headers, but they rarely contain HTML tags.

Oh, great :) Thanks
I could put this in an external form (not really sure how this goes).

Quite easily. First enable Advanced options on Admin prefs tab. Then go there and create a mediatyped custom form type, say
[txt]
title="Plain text"
mediatype="text/plain"Next, create a txt-type form, say headers:
<txp:article_custom>
<txp:etc_query data='<txp:body />' query="//h2|//h3" />
</txp:article_custom>and access it via ?f=headers URL.
And if you prefer to output it in Textile format, this should do:
<txp:article_custom>
<txp:etc_query data='<txp:body />' query="//h2|//h3">
{#}. {?}
</txp:etc_query>
</txp:article_custom>Offline

Woha, don’t even have to think through all this. My answer is serve on a platter !
Thanks again.
This going to be much easier to re model the structure of my website.
