XPointer

• You have to have an named anchor already in the document you point to

• Don't need an anchor
• Only renders the pertinant part of the document
• Example
• http://www.mysite.com/catalog/catalog.xml#xpointer(book1)
• this would point to the element with the ID: book1 in the catalog.xml document

  
        <Catalog> 
            <Book color="red" ID="book1"> 
                  <Title>XML IE5 Programmer's Reference</Title> <Pages>480</Pages> 
                  <ISBN>1-861001-57-6</ISBN> 
                  <RecSubjCategories> 
                        <Category>Internet</Category> 
                        <Category>Web Publishing</Category> 
                        <Category>XML</Category> 
                  </RecSubjCategories> 
                  <Price>$29.99</Price>
             </Book> 
         </Catalog>
