newline

问题 I've stumbled in a problem handling the \line-feed and \carriage-return characters in xml. I know that, according to http://www.w3.org/TR/REC-xml/#sec-line-ends, xml processors are required to replace any "\n\r" or lone "\r" sequences with "\n". The specification states that this has to be the behaviour for handling any "external parsed entity", does this apply to CDATA sections inside of an element as well? thank you, Michele I'm sure that msxml library for example converts every \n\r" or

问题 I have an input C file (myfile.c) that looks like this : void func_foo(); void func_bar(); //supercrazytag I want to use a shell command to insert new function prototypes, such that the output becomes: void func_foo(); void func_bar(); void func_new(); //supercrazytag So far I've been unsuccessful using SED or PERL. What didn't work: sed 's|\n\n//supercrazytag|void func_new();\n\n//supercrazytag|g' < myfile.c sed 's|(\n\n//supercrazytag)|void func_new();\1|g' < myfile.c Using the same

问题 I'm starting to learn perl, using the Wrox Beginning Perl available on perl.org and have a question regarding a for loop example they provide in Chapter 3. #!/usr/bin/perl use warnings; use strict; my @count = (1..10); for (reverse(@count)) { print "$_...\n"; sleep 1; } print "Blast Off!\n" This is the script they provide, and it works as expected. It displays a number followed by ... every second, waiting a second in between each number. When done, it displays Blast Off! However if I remove

问题 I am taking a training course on "C" and running into a problem. It's hard to explain so I'll post the code. This is training syntax, so don't ask me why it's done the way it is. When both of these segment blocks are run in a main(), the second block does not behave as if it exists alone in the main(). I have tried several IDE thinking it might be a bug. /* First Segment Block */ int c; printf("Type a letter: "); c = getchar(); printf("You typed '%c'\n",c); /* OR - outputs the same, to

问题 Does anyone know what this warning is referring to and how I would go about resolving it? [Deprecation] Resource requests whose URLs contain raw newline characters are deprecated, and may be blocked in M60, around August 2017. Please remove newlines from places like element attribute values in order to continue loading those resources. See https://www.chromestatus.com/features/5735596811091968 for more details. 回答1: From what I found elsewhere, this is caused by having a new line character

问题 I want to remove all the line breaks and carriage returns from an XML file so all tags fit on one line each. XML Source example: <resources> <resource> <id>001</id> <name>Resource name 1</name> <desc>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas nibh magna, fermentum et pretium vel, malesuada sit amet dolor. Morbi dictum, nunc sed interdum facilisis, ligula enim pharetra tortor, at egestas urna massa non nulla.</desc> </resource> <resource> <id>002</id> <name>Resource name

问题 So I have an old repo, with many files, some are CRLF, some are LF. I want to (1) change ALL files to LF (I have used dos2unix to convert my files, but git commit ignores those changes!) I have also set git config --global core.autocrlf to false. (2) prohibit all future checkins that have CRLF or auto-convert them to LF. How do I do so? Sorry for the rant. I have read multiple posts here and I can't believe this is so counterintuitive. I have seem many configs like core.safecrlf, core

问题 I am loading a json file and trying to pull some values then output that group of values by line. The current output looks like this: {"time":"1:2:2","post":"1","user":"4","text":"Masaru Emoto"}{"time":"1:3:8","post":"8","user":"5","text":"Meteors"}{"time":"7:4:5","post":"1","user":"8","text":"Olympics"} And I want it to look like this: {"time":"1:2:2","post":"1","user":"4","text":"Masaru Emoto"} {"time":"1:3:8","post":"8","user":"5","text":"Meteors"} {"time":"7:4:5","post":"1","user":"8",

问题 In C I use "1st line 1\n2nd line" for a newline, but what about VB? I know "1st line" & VbCrLf & "2nd line" but its too verbose, what is the escape char for a newline in VB? I want to print 1st line 2nd line I tried using \n but it always outputs this no matter how many times I run the compiler 1st line\n2nd line Any ideas? 回答1: You should use Environment.NewLine . That evaluates to CR+LF on Windows, and LF on Unix systems. There are no escape sequences for CR or LF characters in VB. And that

问题 Introduction I have a C++ process called MyProcess that I call nbLines times, where nbLines is the number of lines of a big file called InputDataFile.txt in which input data are to be found. For example the call ./MyProcess InputDataFile.txt 142 Inform MyProcess that the input data are to be found at the line 142 of the InputDataFile.txt file. Issue The issue is that InputDataFile.txt is so big (~ 150 GB) that the time for searching the correct line is not negligible. Inspired form this post,
