问题 as discussed in an other thread How to avoid cmd.exe interpreting shell special characters like < > ^ it is not easy to get all parameters from the command line. A simple set var=%1 set "var=%~1" are not enough, if you have a request like myBatch.bat abc"&"^&def I have one solution, but it needs a temporary file, and it is also not bullet proof. @echo off setlocal DisableDelayedExpansion set "prompt=X" ( @echo on for %%a in (4) do ( rem #%1# ) ) > XY.txt @echo off for /F "delims=" %%a in (xy

问题 I'm writing the JS for a chat application I'm working on in my free time, and I need to have HTML identifiers that change according to user submitted data. This is usually something conceptually shaky enough that I would not even attempt it, but I don't see myself having much of a choice this time. What I need to do then is to escape the HTML id to make sure it won't allow for XSS or breaking HTML. Here's the code: var user_id = escape(id) var txt = '<div class="chut">'+ '<div class="log" id=

问题 I have a string that contains invalid XML characters. How can I escape (or remove) invalid XML characters before I parse the string? 回答1: As the way to remove invalid XML characters I suggest you to use XmlConvert.IsXmlChar method. It was added since .NET Framework 4 and is presented in Silverlight too. Here is the small sample: void Main() { string content = "\v\f\0"; Console.WriteLine(IsValidXmlString(content)); // False content = RemoveInvalidXmlChars(content); Console.WriteLine

问题 I want to search with grep for a string that looks like this: something ~* 'bla' I tried this, but the shell removes the single quotes argh.. grep -i '"something ~* '[:alnum:]'"' /var/log/syslog What would be the correct search? 回答1: grep -i "something ~\* '[[:alnum:]]*'" /var/log/syslog works for me. escape the first * to match a literal * instead of making it the zero-or-more-matches character: ~* would match zero or more occurrences of ~ while ~\* matches the expression ~* after something

问题 Spent some time troubleshooting a problem whereby a PHP/MySQL web application was having problems connecting to the database. The database could be accessed from the shell and phpMyAdmin with the exact same credentials and it didn't make sense. Turns out the password had a $ sign in it: $_DB["password"] = "mypas$word"; The password being sent was "mypas" which is obviously wrong. What's the best way to handle this problem? I escaped the $ with a \ $_DB["password"] = "mypas\$word"; and it

问题 On an older server I'm using that I can't use prepared statements on I am currently trying to fully escape user input before sending it to MySQL. For this I am using the PHP function mysql_real_escape_string . Since this function does not escape the MySQL wildcards % and _ I am using addcslashes to escape these as well. When I send something like: test_test " ' to the database and then read it back the database shows: test\_test " ' Looking at this I can't understand why the _ has a preceding
