Dcef4 Icefdomedocument getelementsbyclassname and getelementsbyname function

[salvadordf]

Hi phuoc_89,

I'm afraid CEF3 doesn't include those functions in the Document node and CEF4Delphi can only show what CEF3 allows to see.

Here's the CEF3 source code of the cef_domdocument_t struct. This becomes TCefDomDocument and ICefDomDocument in CEF4Delphi.

You can find this in /include/capi/cef_dom_capi.h

I've uploaded a new version of the MiniBrowser demo with a DOM search demo function. (check the DPR file)
It shouldn't be too difficult to create a recursive function that compares element names or class names.
