You can write some pretty simple regular expressions to handle this, or go via more traditional string splitting + LINQ methodology. Regex var linkParser = new Regex(@”\b(?:https?://|www\.)\S+\b”, RegexOptions.Compiled | RegexOptions.IgnoreCase); var rawString = “house home go www.monstermmorpg.com nice hospital http://www.monstermmorpg.com this is incorrect url http://www.monstermmorpg.commerged continue”; foreach(Match m in linkParser.Matches(rawString)) MessageBox.Show(m.Value); Explanation Pattern: \b -matches … Read more
A faster and easier-to-understand filter that accomplishes the same thing: git filter-branch –index-filter ‘ git read-tree –empty git reset $GIT_COMMIT — $your $files $here ‘ \ — –all — $your $files $here
There is a string function (strtok) which can be used to split a string into smaller strings (tokens) based on some separator(s). For the purposes of this thread, the first word (defined as anything before the first space character) of Test me more can be obtained by tokenizing the string on the space character. <?php … Read more
>>> import numpy as np >>> A = np.array([[1,2,3,4],[5,6,7,8]]) >>> A array([[1, 2, 3, 4], [5, 6, 7, 8]]) >>> A[:,2] # returns the third columm array([3, 7]) See also: “numpy.arange” and “reshape” to allocate memory Example: (Allocating a array with shaping of matrix (3×4)) nrows = 3 ncols = 4 my_array = numpy.arange(nrows*ncols, dtype=”double”) … Read more
I know that the original question is solved, nevertheless, I am posting this answer in case anyone else got stuck like I did. Since yesterday, I have tried everything, and I mean everything to do this. All available Java libraries are either out of date, not maintained anymore or lack any kind of usable documentation … Read more
There may be some difficulty in doing this reliably. The problem is that PDF is a presentation format which attaches importance to good typography. Suppose you just wanted to output a single word: Tap. A PDF rendering engine might output this as 2 separate calls, as shown in this pseudo-code: moveto (x1, y); output (“T”) … Read more
Create an element, store the HTML in it, and get its textContent: function extractContent(s) { var span = document.createElement(‘span’); span.innerHTML = s; return span.textContent || span.innerText; }; alert(extractContent(“<p>Hello</p><a href=”http://w3c.org”>W3C</a>”)); Here’s a version that allows you to have spaces between nodes, although you’d probably want that for block-level elements only: function extractContent(s, space) { var span= … Read more
Readability mainly consists of heuristics that “just somehow work well” in many cases. I have written some research papers about this topic and I would like to explain the background of why it is easy to come up with a solution that works well and when it gets hard to get close to 100% accuracy. … Read more
If you only need the dictionary keys 1, 2, and 3 use: your_dict.keys(). If you only need the dictionary values -0.3246, -0.9185, and -3985 use: your_dict.values(). If you want both keys and values use: your_dict.items() which returns a list of tuples [(key1, value1), (key2, value2), …].
