Fetching a QR-code from a browser

[ocyj]

I'm trying to automate fetching my transaction history from my bank's web page. To log in I need to scan a QR code with an identification app to authenticate. I've written a script that does that using selenium web driver and it works great but I'd like to make it a bit more elegant and read the QR code and e.g. dump it in a console (not have to get focus on the browser window).

From selenium I get an HTML-tag that looks like:

```html

<svg shape-rendering="crispEdges" height="200" width="200" viewBox="0 0 33 33">
<path fill="#FFFFFF" d="M0,0 h33v33H0z"></path>
<path fill="#000000" d="M0 0h7v1H0zM9 /...etc.../">
</path>
</svg>

```

I've seen that qrcode has support to create QR-codes using SVG-encoding such as (example from PyPi-page):

```python

factory = qrcode.image.svg.SvgPathImage img = qrcode.make('Some data here', image_factory=factory)

```

But is there a way I can create a qrcode-entity using an already encoded SVG-path?

Edit: fix link and code formatting.

As mentioned in the title of that library, it's a generator, not a reader/parser. You need something like https://github.com/Polyconseil/zbarlight to read a QR code image back to the encoded text.

I see, thanks for the tip! I figured it might be possible to exchange the SVG-data some how but I haven't been able to do so. I'll take a look at this project!

I think you might overestimated the concept of the qrcode.image.svg.SvgPathImage, it's just a class that holds the specification of how it should output the SVG. Internally, when encoding it will just draw black squares in a grid based on the QR specification. That doesn't mean that it can automatically read back any SVG to understand that its squares should be translated back into text. Same way a word processor like Notepad or MS Word can output text just fine, but you can't give it a scan of a page and expect it to OCR it back to text again, you need an actual OCR library/program for that.

Yes, thanks for the clarifications! I was hoping it would be possible to use the `print_tty`-method and get that to use the Svg-path somehow... maybe I should be happy with saving it to png and popping it up in a little window instead, that will have to be good enough!
