Get substring from string in Liquid?

Question

I am working with Jekyll and I have the string balh blah blah&garbage **&*&% garbage <h1>TITLE</h1> &^*$%"

Is there a way to grab TITLE? I have looked at the functions here but I don't see something that I can use.

Answer 1

split to the rescue !

{% assign str = 'garbage <h1>TITLE</h1> moregarbage' %}
{% assign a = str | split: '<h1>' %}

We now have garbage in a[0] and TITLE</h1> moregarbage in a[1]

{% assign b = a[1] | split: '</h1>' %}

We now have TITLE in b[0] and moregarbage in b[1]
