I think your xpath should start from xs:schema or use "//xs:element..."


/xs:schema/xs:[EMAIL PROTECTED]'blah']

Subject:        problem using XPathAPI

Hi,

I tried to use XPathAPI.selectNodeIterator method to get a NodeIterator 
but
I get an error that I don't understand:

org.apache.xpath.XPathException: Can not convert #BOOLEAN to a NodeList!
        at org.apache.xpath.objects.XObject.error(XObject.java:718)
        at org.apache.xpath.objects.XObject.nodeset(XObject.java:448)
        at org.apache.xpath.XPathAPI.selectNodeIterator(XPathAPI.java:175)
        at org.apache.xpath.XPathAPI.selectNodeIterator(XPathAPI.java:152)
        at MapXSLGenerator.generate(MapXSLGenerator.java:80)
        at Mapper.transform(Mapper.java:89)
        at test.main(test.java:27)

Here is the xml:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";> 
 
  <!-- definition of complex type elements -->
  <xs:element name="book">
    <xs:complexType>
      <xs:sequence>
                   <xs:element name="title" type="xs:string"/>
                   <xs:element name="author" type="xs:string"/>
                   <xs:element name="character" minOccurs="0" 
maxOccurs="unbounded">
<xs:complexType>
                 <xs:sequence>
                                   <xs:element name="name" 
type="xs:string"/>
                                   <xs:element name="friend-of" 
type="xs:string"
minOccurs="0"
maxOccurs="unbounded"/> 
                 </xs:sequence>
                     </xs:complexType>
                   </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>

</xs:schema>

I am trying to get xs:elment name="book".

The code is:

NodeIterator nl = XPathAPI.selectNodeIterator(scRoot,
"xs:element/@name=\""+book +"\"");

Note that book is a String containing the value "book".

Please help.

thanks,
Malia
