I'm sorry for the inordinate delay in dealing with these bugs. I decided to put specific bugs on the back-burner and focus my efforts on developing a test suite for Saxon-CE that would in future catch these and many others. I'm not quite there yet but I'm making progress.

These two bugs are both now fixed. However, there's quite a bit more work to be done on regular expressions, even without worrying too much about subtleties like matching non-BMP characters. Apart from anything else, the design overlooked the fact that in Javascript, a compiled regular expression is a mutable object - it starts matching where the previous match left off.

Dear Michael,

there are two more issues:

true() gives an error, already at compile time. Declaring the following function, even without actually invoking it, will raise an error as displayed on attached screenshot (tested in Chrome 11, IE 9, FF 4).

  <xsl:function name="my:true" as="xs:boolean">
    <xsl:sequence select="true()" />
  </xsl:function>

"1 cast as xs:boolean" seems to work instead (also does false()).

In addition, tokenize() seems to send the JS engines into an infinite loop. Can you reproduce this?

Dear Michael,

When using ixsl:eval, I always get back the argument to ixsl:eval itself.

For example, when I view
http://www.saxonica.com/ce/demos/jstest/jstest.html in Firefox 4 or
Chrome 11, it says:

Evaluate Javascript Expressions
2 + 2 is: 2 + 2

instead of
2 + 2 is: 4

In IE 9, however, I get an XPathException.
