问题 I need to turn HTML into plain text. There's a nice function that does that in ActionView's SanitizeHelper, but I have trouble understanding how I can reference it and use it in a simple test.rb file. http://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html I would like to be able to call strip_tags("<b>lol</b>") => "lol" 回答1: The question is quite old, but I had the same problem recently. I found a simple solution: gem sanitize. It's light, works fine and has additional

问题 I have some text file like this, with several 5000 lines: 5.6 4.5 6.8 "6.5" (new line) 5.4 8.3 1.2 "9.3" (new line) so the last term is a number between double quotes.

Python's equivalent to PHP's strip_tags? http://php.net/manual/en/function.strip-tags.php There is no such thing in the Python standard library.

I know this is not quite a data visualization issue, but the boss asked for it, so I need to figure out if it is possible. Thanks! Dave An answer for those searching in 2016.

If "x", the top labels will be displayed to the bottom. If "y", the right-hand side labels will be displayed to the left. Can also be set to "both". ggplot(...) + ... + facet_grid(facets, switch="both") As of ggplot2 2.2.0 , Strips can now be freely positioned in facet

阅读更多关于 How to remove extra indentation of Python triple quoted multi-line strings?

问题 I have a python editor where the user is entering a script or code, which is then put into a main method behind the scenes, while also having every line indented. The problem is that if a user has a multi line string, the indentation made to the whole script affects the string, by inserting a tab in every space. A problem script would be something so simple as: """foo bar foo2""" So when in the main method it would look like: def main(): """foo bar foo2""" and the string would now have an

问题 We've recently been asked to ship a Linux version of one of our libraries, previously we've developed under Linux and shipped for Windows where deploying libraries is generally a lot easier. The problem we've hit upon is in stripping the exported symbols down to only those in the exposed interface. There are three good reasons for wanting to do this To protect the proprietary aspects of our technology from exposure through the exported symbols. To prevent users having problems with
