Ben, I think the problem is deeper than you described. For example: ******** XML data ******** <library xmlns="http://www.library.com"> <book> <title>B1</title> <author>A1</author> <abstract>xyzzy</abstract> </book> <book> <title>B2</title> <author>A2</author> <abstract>xyzzy</abstract> </book> <book> <title>B3</title> <author>A1</author> <abstract>xyzzy</abstract> </book> </library> ********* XLink linkbase *********** <linkbase xmlns:xlink="http://www.w3.org/1999/xlink"> <link xlink:type="extended" xlink:title="Books by Author A1"> <resource xlink:type="locator" xlink:href="library.xml#xpointer(book[position()=1])" xlink:title="B1"/> <resource xlink:type="locator" xlink:href="library.xml#xpointer(book[position()=3])" xlink:title="B3"/> </link> </linkbase> ********* XSLT stylesheet ********* <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:lib="http://www.library.com" xmlns="http://www.w3.org/1999/xhtml"> <xsl:template match="lib:library"> <html> <h1>Books by Author A1</h1> <p> These books come from library XYZ. </p> <xsl:apply-templates/> </html> </xsl:template> <xsl:template match="lib:book[author='A1']"> <p> <b><xsl:value-of select="title"/></b><br> <xsl:value-of select="abstract"/> </p> </xsl:template> </xsl:stylesheet> ******************************** The resulting HTML file will be (not valid, but it's only an example): <html> <h1>Books by Author A1</h1> <p> These books come from library XYZ. </p> <p> <b>B1</b><br> xyzzy </p> <p> <b>B3</b><br> xyzzy </p> </html> Now the question is: Is there any chance for the browser, given the linkbase from above, to know that there should be a link between books B1 and B3? And if, which elements should be used as source and target of the link? the <p> element or the <b> element? In my opinion, there's no general solution to this problem if the complexity of XPointer and XSLT is considered. Michael
