insert html into ElementTree without parsing it

[graeme.pietersz]

I am building HTML pages using ElementTree.

I need to insert chunks of untrusted HTML into the page. I do not need or want to parse this, just insert it at a particular point as is.

The best solutions I can think of are rather ugly ones: manipulating the string created by tostring.

Is there a nicer way of doing this? Is it possible, for example, to customise how an element is converted to a string representation? I am open to using something else (e.g. lxml) if necessary.

How would you want to find out if it can be safely inserted or not without
parsing it?

lxml has a tool to discard potentially unsafe content from HTML files:
