Ability to apply special reformatting filter for 'source:'.. entries - '|pretty' (or jinja2 template filters on the 'filters')

[dgtlmoon]

Example - You are watching the contents of a <select> list from a source:http://foobar website

You add |pretty to your CSS or xPath filter (maybe this should not be available for xpath)

and then you add a extract filter to just extract one line, but the whole list appears as one line of text

URL | https://foobar.com/page.html
FILTER | #id-of-selectbox|pretty
EXTRACT FILTER | /.+W36.L34.*/i

then, the whole select/option list is nicely formatted and I can extract the text of that one <option> value

for example

<select aria-label="Please select a Größe" class="x-msku__select-box" id="x-msku__select-box-1001" selectboxid="1001" selectboxlabel="Größe"><option value="-1">- Select -</option><option disabled="disabled" id="x-msku__option-box-1" value="1"> W30/L30   (Out of stock)</option>

becomes

<select aria-label="Please select a Größe" class="x-msku__select-box" id="x-msku__select-box-1001" selectboxid="1001" selectboxlabel="Größe">
 <option value="-1">
  Select 
 </option>
 <option disabled="disabled" id="x-msku__option-box-1" value="1">
  W30/L30   (Out of stock) 
 </option>
</select>   

Further -

We could use any jinja2 filter, as well as add custom filters, the filter does not have to be source: based filter

|capitalize |lower |pretty, maybe even custom ones like |regex(/../) and more fancy ones like |send(http://someservice.com)

using jinja2, they could be also chained

|int|if int > 10

pipe | is used by both CSS and xPath, need a different filter char
