newline

问题 Is it possible to split a text from a tag by br tags? I have this tag contents: [u'+420 777 593 531', <br/>, u'+420 776 593 531', <br/>, u'+420 775 593 531'] And I want to get only numbers. Any advices? EDIT: [x for x in dt.find_next_sibling('dd').contents if x!=' <br/>'] Does not work at all. 回答1: You need to test for tags , which are modelled as Element instances. Element objects have a name attribute, while text elements don't (which are NavigableText instances): [x for x in dt.find_next

问题 How does one determine the environment newline 1 in C++? Google yields many results for C# and .NET but I didn't see any way to do it for non-CLI C++. Additional info: I need to scan a const char* for the character(s). 1 By "environment newline" I mean \r\n on Windows, \n on Linux, and \r on Mac. 回答1: std::endl inserts a newline appropriate for the system. You can use a ostringstream to determine the newline sequence as a string at runtime. #include <sstream> int main() { std::ostringstream

问题 I am fetching data using tSoap component in which i am getting result in XML format as comma separated values. In which columns are separated by comma and rows are separated by '\n'. After that i am using tExtractXMLField component for extracting data from the response. But in data i have '\n' within the strings which is treating it as a new row. I tried using tReplace component to remove \n within the quotes using regex but data is too large, result causing StackOverflowError. Also I tried

问题 When I save lines of data in excel files as tab delimited .txt files, and then open those files in VIM, I see that what was once a multi-line file in excel is now a single line file in VIM. The "lines" can be separated in VIM using some substitution commands: %s/^M/\r\n/g After this, the "lines" are now separated by an ^@ . I deal with it using another substitution command: %s/^@//g My questions are: Why do my multi-line txt excel files open as a single line in VI? What is ^@ ? Is there a

问题 I have some text files copied out to a server. I typically use and prefer notepad++ to look at text files but on this server, only textpad is installed. This is really strange behavior but I noticed that when I view the EOL chars in notepad++ I can clearly see and search for the CRLF (i.e. \r\n). But when I display the same files in textpad, I am able to search only on the LF (\n) and do not have any hits on the CR (\r). Am I missing something on how Textpad is interpreting the EOL chars? 回答1

问题 I have a very long text file that I'm trying to process using Python. However, the following code: for line in open('textbase.txt', 'r'): print 'hello world' produces only the following output: hello world It's as though Python thinks the file is only one line long, though it is many thousands of lines long, when viewed in a text editor. Examining it on the command line using the file command gives: $ file textbase.txt textbase.txt: Big-endian UTF-16 Unicode English text, with CR line

问题 I am using TinyMCE to provide a rich text editing text editor. But the line spacing between the lines is too much. I have added a screenshot that shows the line spacing I get on pressing an enter. What can be done about it 回答1: There is a css class that is applied to the TinyMCE html content. It looks like you have <p> tags causing the spacing. Honestly, it looks pretty good to me. But you can override in the css class: .tinymce-content p { padding: 0; margin: 2px 0; } See the tinymce docs

问题 I have a TextArea() that I'm collecting user input from. I'd like to spit this input back out into an email, but it's important to preserve the formatting. If someone puts in returns or paragraphs to separate their statements, I want that to be reflected in the output. Currently, I have this input assigned to a variable, and then I reference the variable in the MailApp() call. It is not preserving formatting through this process: var user_input=e.parameter.text_area_input; MailApp.sendEmail({

问题 Is there a shorthand for a new line character in Scala? In Java (on Windows) I usually just use "\n", but that doesn't seem to work in Scala - specifically val s = """abcd efg""" val s2 = s.replace("\n", "") println(s2) outputs abcd efg in Eclipse, efgd (sic) from the command line, and abcdefg from the REPL (GREAT SUCCESS!) String.format("%n") works, but is there anything shorter? 回答1: Your Eclipse making the newline marker the standard Windows \r\n, so you've got "abcd\r\nefg". The regex is
