Browser freeze with 833kb of XML

[stuaxo]

I've got a moderately large amount of XML (833kb), and the browser just locks it up.

Unfortunately I can't share the XML.

I don't know if this is plausible in Jupyter, but would it be possible to stream the output to the browser ?

If I just print() the output everything works.
Using display(XML(my_xml)) the browser stops and eventually I get a firefox popup asking if I want to stop or wait for the page.

It's the browser end freezing, not the python end.

I put in some code to time things and it was about 0.02seconds, while Firefox waited about 5 minutes with 99% cpu.
I put in a sleep(4) it displayed about 4.02 seconds while Firefox had waited about 5 minutes with 99% cpu.

If I remove the call to display(XML(xml)) then there is no delay in Firefox.
If I display just the string of the XML display(xml) then there is no delay in Firefox.

I wonder if this is a Jupyter bug ?

I tried saving the output of XML(xml) into a string instead of displaying it, and it was basically instant.

In the next cell I ran the cell with just the string and reproduced the freeze.

Oh no, it has the same effect, just loading the notebook in the browser where it was previously rendered.
