XSLT Bitwise Logic

Question

I have an existing data set that utilizes an integer to store multiple values; the legacy front end did a simple bitwise check (e.g. in C#: iValues & 16 == 16) to see if

Answer 1

XSLT does not define bitwise operations. If you want them, you have to roll your own.

If you're using XSLT specifically in .NET 2.0 context - that is, XslCompiledTransform class - then the simplest solution is to use a scripting block to introduce a C# function that does it, and then just call that:

  
  
  

  ...

  
  
  ...

Or you can define the more high-level primitives in a scripting block, such as HasFlag, and then use those.

When loading such a stylesheet, you will need to explicitly enable scripting in it:

XslCompiledTransform xslt = new XslCompiledTransform();
xslt.Load("foo.xsl",
  new XsltSettings { EnableScript = true },
  new XmlUrlResolver());
