For example, asking the query /svg/rect/@width with a number return type on the following document: <svg><rect width="100"/><rect width="200"/><svg> This isn't a problem. Like all location paths, /svg/rect/@width returns a node-set, not a number. number(/svg/rect/@width) returns a single number equal to 100; that is it converts only the first node in the set. I don't think there's anything in standard XPath 1.0 that returns more than one number, boolean, or string. -- +-----------------------+------------------------+-------------------+ | Elliotte Rusty Harold | elharo@metalab.unc.edu | Writer/Programmer | +-----------------------+------------------------+-------------------+ | The XML Bible, 2nd Edition (Hungry Minds, 2001) | | http://www.ibiblio.org/xml/books/bible2/ | | http://www.amazon.com/exec/obidos/ISBN=0764547607/cafeaulaitA/ | +----------------------------------+---------------------------------+ | Read Cafe au Lait for Java News: http://www.cafeaulait.org/ | | Read Cafe con Leche for XML News: http://www.ibiblio.org/xml/ | +----------------------------------+---------------------------------+
