问题 Based on the following XML, what is the best way to achieve an alphanumeric sort in XSL? Edit : to clarify, the XML below is just a simple sample the real XML would contain much more variant values. <colors> <item> <label>Yellow 100</label> </item> <item> <label>Blue 12</label> </item> <item> <label>Orange 3</label> </item> <item> <label>Yellow 10</label> </item> <item> <label>Orange 26</label> </item> <item> <label>Blue 117</label> </item> </colors> E.g. I want a final outcome in this order:

问题 In perl s/[^\w:]//g would replace all non alphanumeric characters EXCEPT : In python I'm using re.sub(r'\W+', '',mystring) which does remove all non alphanumeric except _ underscore. Is there any way to put exceptions, I wish not to replace signs like = and . Previously I was applying the other approach i.e. to replace all unwanted characters using re.sub('[!@#\'\" $()]', '',mystring`) However, it is not possible for me to predict what all characters may come in mystring hence I wish to

问题 For example !@#123myname --> myname !@#yourname!@#123 --> yourname!@#123 There are plenty of S.O. examples of "most pythonic ways of removing all alphanumeric characters" but if I want to remove only non-alphabet characters leading up to first alphabet character, what would be the best way to do this? I can do it with a while loop but im looking for a better python solution 回答1: If you want to remove leading non-alpha/numeric values: while not s[0].isalnum(): s = s[1:] If you want to remove

问题 I want to sort all columns of a data frame in R by a column containing alphanumeric data. Here is an example data frame: R> dd <- data.frame(b = c("Hi", "Med", "Hi", "Low"), x = c("A", "D", "A", "C"), y = c(8, 3, 9, 9), z = c("A1", "A3", "A10", "A2")) 1 Hi A 8 A1 2 Med D 3 A3 3 Hi A 9 A10 4 Low C 9 A2 I would like to sort the entire data frame on column z. The desired output looks like this - with the info across columns staying consistent: 1 Hi A 8 A1 2 Low C 9 A2 3 Med D 3 A3 4 Hi A 9 A10

问题 I have a data frame which stores a count value for each model. Model name is an alphanumeric. Then I generate a bar plot using ggplot2 having the models in the x axis and the count in the y axis. I want to order my x axis. The x axis appears as follows in the data frame and in the x axis in the plot. I want to sort it properly for example, M_1, M_2, M_3, M_10, M_11, M_20 etc Model Count M_1 73 M_10 71 M_100 65 M_11 65 M_110 64 M_111 71 M_13 70 M_130 73 M_2 72 M_20 69 M_200 63 M_21 72 M_210 72

问题 I am trying to separate non-numbers from numbers in a Python string. Numbers can include floats. Examples Original String Desired String '4x5x6' '4 x 5 x 6' '7.2volt' '7.2 volt' '60BTU' '60 BTU' '20v' '20 v' '4*5' '4 * 5' '24in' '24 in' Here is a very good thread on how to achieve just that in PHP: Regex: Add space if letter is adjacent to a number I would like to manipulate the strings above in Python. Following piece of code works in the first example, but not in the others: new_element = [
