 I hereby prpose a solution to the problem you posted on mulberry. In your xslt, use <xsl:value-of select="following-sibling::book[last()]/title"/> and <xsl:value-of select="following-sibling::book[last()]/series/@number"/> instead of <xsl:value-of select=".[last()]/title"/> and xsl:value-of select=".[last()]/series/@number"/> respectively. You need to do this because when you write <xsl:for-each-group select="book[series and date-read]" group-by="series/@title"> your context node becomes that book element whose series/@title value is unique from the values processor found earlier. Hence, not all book elements will enter this loop (I think this is what you thought when you wrote . instead of following-sibling), only two book nodes will enter this for-each-group loop i.e. the first book element whose series/@title value is Hitchhiker Series and the first book element whose series/@title value is The Magic of Xanth and all other members in their corressponding groups become the context book node's following sibling. Can you let me know what do you exactly want to do with book numbers with an example and where do you want to write this condition, inside the for-each-group loop or somewhere else? Will definitely try to help you out.

I want to get the last book that I've read in each series. I tried to use XML groups and get the last() item, but it's not working as I expected: it always comes up as the first book in the series. What I'm a going wrong? As an aside, I eventually also want to look through the books for missing books (starting with 1 and ignoring any series with a non-integer number, like "3.5" -- which I use to represent a short story that comes in the storyline at that point.) NOTE: Since I could not get the last number in the series, I have not even attempted this in the XSLT file yet. I've included some sample files at the end of the text: text.xml (the input) and toread.xsl (the XSLT). This is the command I'm using: java -jar saxon9he.jar -s test.xml -o toread.txt toread.xsl I've included the received output (toread.txt) and the expected output (toread-expected.txt). Any pointers appreciated. Thanks.
