Re: SUMMARY: Re: Sorting on a variable
PS sum(price[@curr='xxx']) is probably quicker and better than concat('0',price[@curr='xxx']) especially if there is any chance of white space in the input <price curr='xxx'> 1213 </price> would kill the concat('0' construction. In either case of course, th epoint is is to produce a version of price[@curr='xxx'] which acts as 0 rather than NaN in the case that there is no element with that attribute.
