Flip most of an svg image, but not the text within it

Manipulating the SVG, all you need to do is

move the <text> elements outside the group with the transform attribute
recompute the y attribute with
```
y -> 940 - y
```
This supposes that the transform attribute is always transform="scale(1, -1) translate(0, -900)" and the font size 80px. A general formula would be
```
y -> (negative y translation + font size / 2) - y
```

Here is a node script utilizing cheerio to change existing files:

const cheerio = require('cheerio');const $ = cheerio.load(xmlText, { xmlMode: true });function flipTextInPlace ($) {    $('text').each(() => {       const y = $(this).attr('y');       $(this).attr('y', 940 - y);    }).appendTo('svg');}

javascript css node.js svg

I hope this helps:

text:nth-child(1) {  transform: scale(1, -1);  transform-origin: 317px 812px;/*same as text coords*/  dominant-baseline: hanging;}

Unfortunately this works on Chrome & Firefox but not on Safari. Didn't check Edge & IE.

javascript css node.js svg

You could use css transform on your text nodes

Edit

Inspired from @enxaneta answer, you could run this little script

const text = document.querySelectorAll("text");text.forEach(function(el){     el.style.transformOrigin = el.getAttribute('x')+'px '+el.getAttribute('y')+'px';  el.style.transform = "scale(1,-1)";     });

text{  dominant-baseline:central;}
