I'm using blogger to make a podcast. It works really well, but I find myself copy/pasting a lot of things, when two or three variables and a template would do the job really well.

Most of the posts look like this:

```
Étude de Exode 6.14-7.13.
<br />
<audio controls>
  <source src="file.mp3" type="audio/mpeg">
  <embed height="50" width="100" src="file.mp3">
</audio>

<biblia:bible layout="minimal" resource="lsg" width="400" height="600" historyButtons="false" navigationBox="false" resourcePicker="false" shareButton="false" textSizeButton="false" startingReference="Ex6.14-7.13"></biblia:bible>

```

Where three things change:

* the text on top ("Étude de Exode 6.14-7.13." in the example)
* the link to the sound file (which is actually `data:post.link`, but I can't seem to be able to use `expr:src` there unfortunately)
* the references passed to the `biblia:bible` tag (here 'Ex6.14-7.13')

Is there a way I could use a template and variables for my blog posts instead of copying and changing things manually every time?
