newline

问题 I have a PHP webservice that returns an XML output, and one of the Tag contains a multiline "\n" String data. My problem is, all "\n" is being removed after I pass the XML data through the default SAX parser, but I really dont want this to happen! I want to retain all newline "\n" characters within the Tag so that I can extract it and display them in a simple TextView or EditText. I tried a couple of workarounds like substituting the "\n" with "&x#dA;" or something, but I cant get it to work

问题 So I just reformatted a bunch of code to incorporate textwrap.wrap, only to discover all of my \n are gone. Here's an example. from textwrap import wrap def wrapAndPrint (msg, width=25): """ wrap msg to width, then print """ message = wrap(msg, width) for line in message: print line msg = ("Ok, this is a test. Let's write to a \nnewline\nand then " "continue on with this message") If I print msg, I get the following >>> print msg Ok, this is a test. Let's write to a newline and then continue

问题 I want to write text files with DOS/Windows line endings '\r\n' using python running on Linux. It seems to me that there must be a better way than manually putting a '\r\n' at the end of every line or using a line ending conversion utility. Ideally I would like to be able to do something like assign to os.linesep the separator that I want to use when writing the file. Or specify the line separator when I open the file. 回答1: Just write a file-like that wraps another file-like and which

问题 I'm storing text in a sqlite file and setting the text of a UITextView to be the value of that text. The only problem is that the UITextView isn't honoring the newline character. Instead, it's printing it out as text. Here's an example: Stored in fruit.sqlite and passed to theFruit object: requiredFruit = "apples\n oranges\n pears" NSString *theFruit = [NSString stringWithFormat:@"%@", theFruit.requiredFruit]; generalOutlet.text = theFruit; It Displays apples\n oranges\n pears but I want it

问题 I have a bunch of textfile that looks like this: His doctor attributed this to an allergy . That hardly convinced him , as he had no history of allergies of any kind . " Yet , that was to be the least of his problems . I may have to take steroids for the rest of my life . " A topical steroid spray was later added to his repertoire of drugs and " he knew it was merely masking the underlying condition . " And I want to change it such that the . " are in a single line. The desired output should

问题 I am printing a string to the python shell on a mac os 10.7.3. The string contains new line characters, \n\r, and tabs, \t. I'm not 100% sure what new line characters are used on each platform, however i've tried every combination (\n, \n\r, \r) and the newline characters are printed on the shell: 'hello\n\r\tworld' I don't know what i'm doing wrong, any help is appreciated. Thanks 回答1: What look to you like newlines and carriage returns are actually two characters each -- a back slash plus a

问题 I'm working on a JavaScript assignment that requires me to use prompt-synch in Node.JS. It works fine until I try to use a newline character \n within the prompt, at which point every character or backspace typed causes the prompt to repeat itself. What could I do to get the user input to appear on a new line (a requirement of this exercise) without this issue? Problem code: if (guess < answer) { guess = prompt("Too low!\n> "); } else if (guess > answer) { guess = prompt("Too high!\n> "); }

问题 I am trying to craft a macro replacing newlines. My first try was: define(`m4_pascal_str',` patsubst(`$1',`^\(.*\)$',`\1++') ') m4_pascal_str(` 11 22 33 44 ') define(zz,` 11 22 33 44 ') m4_pascal_str(`zz') That gives correct answer when not using intermediate macro, and match only last newline otherwise. See results below: ++ ++ 11++ ++ 22 33 44++ ++ 11 22 33 44 ++ Then I found similar question: in m4's patsubst, how do I replace newlines with spaces? So, I just made: define(`m4_pascal_str',`

问题 I am saving news from textarea in database and showing them again on a JSF page. When I print the bean data I have it as below. This is line 1 This is line 2 In textarea when I try to edit, I see same as above. But when I try to print in <h:outputText> I see it as below. This is line 1 This is line 2 Even when I print using Sytem.out.println() , I see output as This is line 1 This is line 2 Any idea how can I get this new line in <h:outputText> ? I also tried this answer which suggests to use

问题 I have a string which contains multiple file paths, some of which contain arbitrary newlines within the path, and I want to parse the string using python so that only the filenames and extensions remain. For example: a/b/c/d/file1.c a/b/c/d/e/f/g/h/1/2/3/4/5/foo.c dir1/dir2/newlinedir /nextlinedir/bar.c should be parsed to give output: file1.c foo.c bar.c I am using the following regular expression (the groups for the filename and extension must be separate for later purposes): path_regex =
