Inverse of DOMDeleteTransformer possible?

[adesso-thomas-lippitsch]

Hi,

I am trying to get the inverse functionality of DOMDeleteTransformer.
I want to keep only the content in the specific CSS selector, instead of removing it from the DOM.
I want to get rid of all the text from menus, banners, navigations, etc. and it is easier and more versatile to spcify which content to keep instead of which not to keep.

Is that somehow possible?

I imagined something like a DOMTransformer which can include and exclude parts of the DOM, analogous to the onMatch=[include|exclude] of the ReferenceFilter.

<handler class="DOMTransformer">
    <dom selector="div#content" onMatch="include" />
</handler>

This has been solved in How to extract the content of only certain tags using css selector.

Therefor I will close this issue.

Thanks a lot!
