Getting the result from xpath+using interfaces

[Maha Hassan]

Dear All,

I am trying to get the results from an xpath excpression but the problem is i do not know how to get it in a nodeset , nodelist or even a normal list
the only thing that is working is a String , so i get only one output

String projectStatements = (String) xpath.evaluate(stmtExpr, inputSource,
XPathConstants.STRING );

when i try writing NodeSet/Nodelist instead of String i get an error ,,what shall i do??

    NodeSet nodes = (NodeSet) xpath.evaluate(stmtExpr, inputSource, 
         XpathConstants.NODESET); 
 
--------------------Configuration: <Default>--------------------
Z:\Java Files\Xpath\erd.java:18: cannot find symbol
symbol  : class NodeSet
location: class org.xml.sax.erd
           NodeSet nodes = (NodeSet) xpath.evaluate(stmtExpr, inputSource, 
           ^
Z:\Java Files\Xpath\erd.java:18: cannot find symbol
symbol  : class NodeSet
location: class org.xml.sax.erd
           NodeSet nodes = (NodeSet) xpath.evaluate(stmtExpr, inputSource, 
                            ^
Z:\Java Files\Xpath\erd.java:19: cannot find symbol
symbol  : variable XpathConstants
location: class org.xml.sax.erd
         XpathConstants.NODESET); 
         ^
3 errors 

I need to loop on all results of the xpath to print them.

Thanks

You need to import the classes you are using properly. Let me move this post to Java in General (Beginner), which would be a more appropriate place for it.

i am importing


package org.xml.sax;
import javax.xml.xpath.*;
what else shall i import??

[Paul Clapham]

The messages tell you that. You need to import the NodeSet and XpathConstants classes from whatever packages they are in.

I don't see them in the API documentation for Java 1.4, which is what I have on my computer here. Perhaps they are in Java 5, which I don't have. Check your Java 5 documentation. And if that is where they are, make sure you are using a Java 5 compiler.

i found that nodelist(instead of nodeset since nodeset is not in java 1.5) is an interface at java 1.5 but i am wondering how to use it ??
