It's common practice to include snippets of one page in another as an image of the rendered content. This has obvious disadvantages, not least that text isn't being represented as text.

Are there any techniques or tools that allow swift excerpting from one web page, and embedding of the excerpted content in another page?

I imagine the excerpting process would have to capture enough stylesheet data to recreate it, as well as work out how to trim down the content to just the area being captured.I imagine the embedding step may use the object element or something like that?

There must be a better way than capturing a rasterised rendering of the web page to be excerpted.
