text-files

问题 I have many HTML files from which I need to extract text. If it's all on one line, I can do that quite easily but if the tag wraps around or is on multiple lines I can't figure how to do this. Here's what I mean: <section id="MySection"> Some text here another line here <br> last line of text. </section> I'm not concerned about the <br> text, unless it will help wrap the text around. The area that I want always begins with "MySection" and then is ended with </section> . What I'd like to end

问题 I have a trouble reading the txt file, which contains 10 columns and 2 lines of header, but the problem is that in the middle of the file the same header appears several times and textread() doesnt function. That's my file example: file.txt headerline1 aaaa headerline2 111 123 20/12/2000 name1 name2 name3... name8 0 21/12/2000 name1 name2 name3... name8 0 22/12/2000 name1 name2 name3... name8 0 headerline1 aaaa headerline2 111 123 25/12/2000 name1 name2 name3... name8 0 27/12/2000 name1 name2

问题 I am writing a TXT file using PHP. I want to insert actual line breaks into the TXT file wherever necessary. I have tried all combinations of \n \r \r\n \n\r ... but these are not causing any linebreaks to appear - in most cases, I am seeing the text "\n" appear in the TXT file, with no linebreak. I have also tried chr(13). Any other ideas would be appreciated. 回答1: Sounds to me like you might be using single quotes, i.e. '\n' rather than "\n" . If you wanted to continue with a single quotes

问题 I know that I can use: gc c:\FileWithEmptyLines.txt | where {$_ -ne ""} > c:\FileWithNoEmptyLines.txt to remove empty lines. But How I can remove them with '-replace' ? 回答1: I found a nice one liner here >> http://www.pixelchef.net/remove-empty-lines-file-powershell. Just tested it out with several blanks lines including newlines only as well as lines with just spaces, just tabs, and combinations. (gc file.txt) | ? {$_.trim() -ne "" } | set-content file.txt See the original for some notes

问题 I am comparing text files in junit using: public static void assertReaders(BufferedReader expected, BufferedReader actual) throws IOException { String line; while ((line = expected.readLine()) != null) { assertEquals(line, actual.readLine()); } assertNull("Actual had more lines then the expected.", actual.readLine()); assertNull("Expected had more lines then the actual.", expected.readLine()); } Is this a good way to compare text files? What is preferred? 回答1: junit-addons has nice support

问题 Consider this python program: import sys lc = 0 for line in open(sys.argv[1]): lc = lc + 1 print lc, sys.argv[1] Running it on my 6GB text file, it completes in ~ 2minutes. Question: is it possible to go faster? Note that the same time is required by: wc -l myfile.txt so, I suspect the anwer to my quesion is just a plain "no". Note also that my real program is doing something more interesting than just counting the lines, so please give a generic answer, not line-counting-tricks (like keeping

问题 I have a repository with a lot of autogenerated source files I've marked as "binary" in .gitattributes (they are checked in because not everyone has access to the generator tools). Additionally, the repo has a lot of source-ish files in ignored directories (again, generated as part of the build processes), and a number of actual binary files (e.g. little resource files like icons). I'd now like to find all the non-auto-generated and non-ignored files in the repo. I thought I'd just do this

问题 How can I fix the script below so that it will work EVERY TIME! Sometimes it works and sometimes it doesn't. Pro JQuery explains what causes this, but it doesn't talk about how to fix it. I am almost positive it has to do with the ajax ready state but I have no clue how to write it. The web shows about 99 different ways to write ajax and JQuery, its a bit overwhelming. My goal is to create an HTML shell that can be filled with text from server based text files. For example: Let's say there is
