问题 I want to retrieve all 3D models on some area from Google Earth. How can this be achieved? 回答1: There is currently no way to download all the models from within Google Earth. Also, even is there was - extracting data is against the TOS.

问题 Users may want to delimit numbers as they want. What is the most efficient (or a simple standard function) to extract all the (natural) numbers from a string? 回答1: You could use a regular expression.
