• How to remove dangerous characters(ie script tags)?

  - by chobo2

  I am wondering is there any sort of C# class or 3rd party library that removes dangerous characters such as script tags? I know you can use regex but I also know people can write their script tags so many ways that you can fool the regex into thinking it is OK. I also heard that HTML Agility Pack is good so I am wondering is there any script removal class made for it?

• How Do I grep For non-ASCII Characters in UNIX

  - by Peter Conrey

  I have several very large XML files and I'm trying to find the lines that contain non-ASCII characters. I've tried the following: grep -e "[\x{00FF}-\x{FFFF}]" file.xml But this returns every line in the file, regardless of whether the line contains a character in the range specified. Do I have the syntax wrong or am I doing something else wrong? I've also tried: egrep "[\x{00FF}-\x{FFFF}]" file.xml (with both single and double quotes surrounding the pattern).

• Allowed characters in linux environment variable names

  - by Christian Semrau

  What characters are allowed in linux environment variable names? My cursory search of man pages and the web did only produce information about how to work with variables, but not which names are allowed. I have a Java program that requires an defined environment variable containing a dot, like com.example.fancyproperty. With Windows I can set that variable, but I had no luck setting it in linux (tried in SuSE and Ubuntu). Is that variable name even allowed?

• C#, XmlDocument, and special ISO Latin characters

  - by Trent

  I'm trying to load up xml into an XmlDocument, but it doesn't recognize the encoded '&eacute' and throws an error 'An error occurred while parsing Entity Name'. Now I can add a custom entity set in a DTD of my xml, so the XmlDocument loads properly. But what I'm hoping is that I can reference a url that has a common set of these ISO Latin encoded characters. Is this possible, or do I need to inject a custom list of DTD sets?
