In the lack of any good free XPath 2.0 implementations for .Net build upon Linq to XML I have thought about implementing my own (also for the experience). But just to be clear (and not building something that exists) these are the XPath 2.0 implementations I have found: Saxon .Net Query Machine - I had problems with this - exceptions with the examples XQSharp - may be good, but is commercial (single developer ~300 $) Now, I want some thoughts on how difficult it is to implementing some language such as XPath 2.0 expressions. I have found this link which have a EBNF for XPath 2.0 expression:

I need to find out the prime factors of over 300 billion. I have a function that is adding to the list of them...very slowly! It has been running for about an hour now and i think its got a fair distance to go still. Am i doing it completly wrong or is this expected? Edit: Im trying to find the largest prime factor of the number 600851475143. Edit: Result: { List<Int64> ListOfPrimeFactors = new List<Int64>(); Int64 Number = 600851475143; Int64 DividingNumber = 2; while (DividingNumber < Number / DividingNumber) { if (Number % DividingNumber == 0) { ListOfPrimeFactors.Add(DividingNumber);

I don't know if it's possible, but I'm wondering how to do it... Let's say we have the following XSL: <xsl:template name="foo"> Bla bla bla </xsl:template> ... <xsl:template name="bar"> Bla bla bla </xsl:template> ... <xsl:template match="/"> <xsl:if test="$templateName='foo'"> <xsl:call-template name="foo"/> </xsl:if> <xsl:if test="$templateName='bar'"> <xsl:call-template name="bar"/> </xsl:if> </xsl:template> Is it possible to change the XSL to read something like... <xsl:template match="/"> <xsl:call-template name="$templateName"/> </xsl:template> No, this is not possible not directly

Several questions about functional programming languages have got me thinking about whether XSLT is a functional programming language. If not, what features are missing? Has XSLT 2.0 shortened or closed the gap? XSLT is declarative as opposed to stateful. Although XSLT is based on functional programming ideas, it is not a full functional programming language, it lacks the ability to treat functions as a first class data type. It has elements like lazy evaluation to reduce unneeded evaluation and also the absence of explicit loops. Like a functional language though, I would think that it can be
