Extract, create and append using xpath and telegram instant view

Question

<iframe src="https://expmle.com/subdirectory/sample_title" />

How can I create and append below <a> tag from above code using XPath and Telegram Instant view functions?

<a href="https://expmle.com/subdirectory/sample_title">sample_title</a>

I want to extract whole src and last part of that and use of them to create <a> tag.

Any suggestions would be very appreciated :)

This should work correctly.

<a>: //iframe # Find iframe and convert it to <a>

@set_attr(href, ./@src) # Set href attribute from src

$anchor # Create variable for current <a>
@set_attr(text, ./@href) # We set new attribute for link which will processed by @match function, then @text attribute will be replaced by result of the @match
@match("\\w+_\\w+"): $@/@text # Now we find our future name of the link "sample_name" (this function will replace all in @text by our new name

@prepend(@text): $anchor # And then put this name to his $anchor

Thank you very much, it almost worked except the last line. `$@` is an attribute node and I don't know why but `@prepend_to` didn't add it as a text of ``. – Alizadeh118 Feb 22 '19 at 14:03
I was trying to use `@prepend($@): $anchor` but it parses `$@` as a string not a variable :( What do you think? – Alizadeh118 Feb 22 '19 at 14:05
Thanks, I needed to change `$@/@text` to `$$/@text` or `$anchor/@text` to get result. – Alizadeh118 Feb 23 '19 at 12:34
Cool! Good luck in the contest :) – haacki47 Feb 23 '19 at 12:36

# append <a> tag below
@after(<a>, href, ./@src, content, ./@src): //iframe

# take everything after the last slash
@match("[^\/]+$", "1"): $@/@content

# move the attribute inside the tag
@append(@content): $@

If the last $@ won't work, just define a variable for <a>.

Thank you very much, yep as you told I needed to define a variable for ``, Also I changed your regex to `"[^\/]+$"` and remove dot-slash(`./`) from `@append(./@content)` and now it works fine. – Alizadeh118 Feb 23 '19 at 12:31
@Alizadeh118 Could you change the best answer then? – xamgore Feb 23 '19 at 13:06
