StringEscapeUtils find out if string is escaped

阅读更多关于 StringEscapeUtils find out if string is escaped

问题 I've been using StringEscapeUtils.escapeHTML to escape URLs. Is there something similar to find out if the string is already escaped? 回答1: Not that I know of, but it is pretty easy to do one yourself: public boolean isEscaped(String url) { return !url.equals(StringEscapeUtils.unEscapeHTML(url)); } Note that deciding if a random string is escaped or not is impossible as @themel notes, you can get a lot of false positives if you try this with random strings. However I'm assuming that you at

Passing a Batch File an Argument Containing a Quote Containing a Space

阅读更多关于 Passing a Batch File an Argument Containing a Quote Containing a Space

问题 On many occasions I have dealt with passing batch files arguments with spaces, quotes, percents, and slashes and all sorts of combinations of them. Usually I managed to figure out how to accomplish what I want, but this time I am stuck. I have tried a couple of hundred combinations now and my head is starting to hurt. I’ve reduced the problem to a—fairly—simple requirement: pass from one batch file to another, an argument that contains some space-delimited text, one of which is a quoted space

问题 I have table named References in SQLite, so I can't target it, it seems. SQLite studio I use to edit databases throws an error. Is there a way to escape database name? The query is: UPDATE References SET DateTimeLastEdited = datetime('now', 'localtime') WHERE NewsItemID = old.NewsItemID; (This is part of the trigger I am making.) 回答1: You can escape table names with double quotes: UPDATE "References" SET DateTimeLastEdited = datetime('now', 'localtime') WHERE NewsItemID = old.NewsItemID;

wcf forces chars escaping in response

问题 I want to return unescaped html in the WCF response, therefore I need CDATA section to be included in the response all the time. I realized I have no chance with DataContractSerializer. So I have tried to mark my operation with [XmlSerializerFormat] and implement IXmlSerializable in the response class. I see that my serialization code is invoked but then it anyway does not work. I am pretty sure now that WCF somehow analyzes the contents of the response and forces chars escaping there in a

How to handle file paths with special characters?

阅读更多关于 How to handle file paths with special characters?

问题 I've got a PowerShell script that needs to be able to call another PS script from within the same directory with elevated credentials. Because the scripts need to be portable, the file path of the scripts isn't known ahead of time and needs to be able to handle spaces and special characters in the file path without failing. Since elevating a PS session will cause the current working directory to change to "C:\Windows\System32", I need to be able to pass the current directory to the script as

阅读更多关于 Validate Unicode String and Escape if Unicode is Invalid (C/C++)

问题 I have a program that reads arbitrary data from a file system and outputs results in Unicode. The problem I am having is that sometimes filenames are valid Unicode and sometimes they aren't. So I want a function that can validate a string (in C or C++) and tell me if it is a valid UTF-8 encoding. If it is not, I want to have the invalid characters escaped so that it will be a valid UTF-8 encoding. This is different than escaping for XML --- I need to do that also. But first I need to be sure
