Hi<div><br></div><div>Can I run dynamic RELATIVE xpath using saxon:evaluate? I retrieve book elements from books.xml file and I want to navigate these elements using relative xpaths and saxon:evaluate. It seems saxon:evaluate understands only absolute paths that starts from the root element.</div>
<div><br></div><div>I am using saxon processor in oXygen.</div><div><br></div><div>The following is sample xquery and data files, my application is different.</div><div><div>XQuery:</div><div><div><Authors></div><div>
{</div><div> (: Step One I get the dynamic path from paths.xml file :)</div><div> let $author_path := data(doc('paths.xml')/Xpaths/Author_Path) </div><div> for $elem2 in doc('Books.xml')/Books/Book (:Get book elements:)</div>
<div> return $elem2/saxon:evaluate($author_path) (: Want to navigate a book element here but it does not work:)</div><div> } </div><div></Authors></div></div></div><div>------------------------------------------------------------</div>
<div>Data file books.xml</div><div><Books></div><div><div> <Book></div><div> <author>John</author></div><div> <Title>XQuery</Title></div><div> </Book></div><div> <Book></div>
<div> <author>Tim</author></div><div> <Title>XSLT</Title></div><div> </Book></div><div></Books> </div></div><div>---------------------------------------------------------------------------------------------</div>
<div>File that contains xpaths that will be loaded and run dynamically</div><div>paths.xml</div><div><div><Xpaths></div><div> <Author_Path> /author[1] </Author_Path></div><div></Xpaths></div></div>
<div>--------------------------------------------------------------------------------------------</div><div><br></div><div>The query returns nothing , when I use static path return $elem2/author[1]</div><div>it works. When I change the path stored in paths.xml to /Books/Book/author[1] it returns all authors in each iteration.</div>
<div><div><Authors></div><div> <author>John</author></div><div> <author>Tim</author></div><div> <author>John</author></div><div> <author>Tim</author></div><div>
</Authors></div></div><div><br></div><div>I appreciate any help</div><div><br></div><div>Thank you</div><div>Hisham</div><div><br></div><div><br></div>
