XPathOnUrl Not Working

I use this code and not working

=Dump(XPathOnUrl(https://womensfitness.co.uk/,"//h2"),TRUE)

How can I scrape and the result looks like this

h1 text
h2 text
h2 text
h3 text
h2 text
h3 text

Looks like you forgot a starting quote in your formula, corrected:

=Dump(XPathOnUrl("https://womensfitness.co.uk","//h2"),TRUE)
