How to Extract Pairs to Dictionary?

Given input like this:

<span class="inplaceeditable inplaceeditable-select" data-inplaceeditable="1" data-component="local_tregister" data-itemtype="cart_item" data-itemid="236756"

    data-value="12" data-editlabel="קבוצת רישום" data-type="select" data-options="[
    {&quot;key&quot;:10,&quot;value&quot;:&quot;10 - 0 \u05de\u05e7\u05d5\u05de\u05d5\u05ea \u05e4\u05e0\u05d5\u05d9\u05d9\u05dd&quot;},
    {&quot;key&quot;:11,&quot;value&quot;:&quot;11 - 7 \u05de\u05e7\u05d5\u05de\u05d5\u05ea \u05e4\u05e0\u05d5\u05d9\u05d9\u05dd&quot;},
    {&quot;key&quot;:12,&quot;value&quot;:&quot;12 - 0 \u05de\u05e7\u05d5\u05de\u05d5\u05ea \u05e4\u05e0\u05d5\u05d9\u05d9\u05dd&quot;},
    {&quot;key&quot;:13,&quot;value&quot;:&quot;13 - 0 \u05de\u05e7\u05d5\u05de\u05d5\u05ea \u05e4\u05e0\u05d5\u05d9\u05d9\u05dd&quot;}]">
        
        <a href="#" class="quickeditlink aalink" data-inplaceeditablelink="1" title="קבוצת רישום">
            12 - 0 מקומות פנויים
            <span class="quickediticon visibleifjs"><i class="icon fa fa-pencil fa-fw "  title="קבוצת רישום" aria-label="קבוצת רישום"></i></span>
        </a>
</span>

What’s the most efficient way (performance is critical to me) to get the following output:

{10:0, 11:7, 12:0, 13:0}

Please Note, I wrote them as numbers for ease of use only but I’m expecting key and value to be strings inside a dictionary.

>Solution :

You can use regex matching with a lookbehind on ; to only catch the relevant data:

import re

data = '''<span class="inplaceeditable inplaceeditable-select" data-inplaceeditable="1" data-component="local_tregister" data-itemtype="cart_item" data-itemid="236756"

    data-value="12" data-editlabel="קבוצת רישום" data-type="select" data-options="[
    {&quot;key&quot;:10,&quot;value&quot;:&quot;10 - 0 \u05de\u05e7\u05d5\u05de\u05d5\u05ea \u05e4\u05e0\u05d5\u05d9\u05d9\u05dd&quot;},
    {&quot;key&quot;:11,&quot;value&quot;:&quot;11 - 7 \u05de\u05e7\u05d5\u05de\u05d5\u05ea \u05e4\u05e0\u05d5\u05d9\u05d9\u05dd&quot;},
    {&quot;key&quot;:12,&quot;value&quot;:&quot;12 - 0 \u05de\u05e7\u05d5\u05de\u05d5\u05ea \u05e4\u05e0\u05d5\u05d9\u05d9\u05dd&quot;},
    {&quot;key&quot;:13,&quot;value&quot;:&quot;13 - 0 \u05de\u05e7\u05d5\u05de\u05d5\u05ea \u05e4\u05e0\u05d5\u05d9\u05d9\u05dd&quot;}]">
        
        <a href="#" class="quickeditlink aalink" data-inplaceeditablelink="1" title="קבוצת רישום">
            12 - 0 מקומות פנויים
            <span class="quickediticon visibleifjs"><i class="icon fa fa-pencil fa-fw "  title="קבוצת רישום" aria-label="קבוצת רישום"></i></span>
        </a>
</span>'''


dict(i.split(' - ') for i in re.findall('(?<=;)(\d+\s-\s\d+)', data))

output:

{'10': '0', '11': '7', '12': '0', '13': '0'}
