Could anyone tell me how I can calculate the length of a string containing
inline elements?

E.g.



With a context node like this:



<text>this is some text<SUP>3</SUP>some more</text>



"string-length(.)" should return 43,

No, it should not return 45 because that is not the number of 
characters in the string value of the <text> element (assuming your 
current node is that element).



but it returns less than that.

I make it 27 by eye.



My assumption is that the embedded tags are being treated as proper nodes
rather than literal text.

Yes, because the syntax used to represent a node is not in the XPath 
data model and therefore is not available to the XSLT processor.



Any idea how I can make sure that each character of the embedded tags counts
as a character when calculating the length of the overall string?

By not using XSLT.



E.g.   <SUP> would count as 5 characters

In XSLT there is no difference in the data model between an element 
represented by:



    <SUP>



or by:



    <SUP                >



... which have a very different number of characters.



You'll have to use something that represents the syntax of XML markup 
in the data model.



I hope this helps.
