RE: Problem with Xpath

[Kakoli]

Hi Jesse,
        Using //operator/database/text() gives me the last value Oracle only, though it iterates through all values.

The values are available by giving the abolute path where context-node is the entire document like:
/config/operator-list/operator[1]/database/text() -------------> MSSQL
/config/operator-list/operator[2]/database/text() -------------> Oracle

But I do not want to use the index. Instead I want to give relative path where the context node is the individual <operator> node. And I want to run it in a for loop. In that case, what should be the XPath?

Xpath operator/database/text() on the first <operator> node as context should return MSSQL.

Xpath operator/database/text() on the second <operator> node as context should return Oracle. But it is giving null.

Thanks & Regards,

Kakoli

try //operator/database/text()

this will match all text nodes under operator/database, no matter where that
structure exists in the doc.

Hi,
I am trying to use XPath feature of Xalan-Java 2.3.1
My xml file looks thus :

<config>

        <params>
                <configDir>xxx</configDir>
                <serverDir>yyy</serverDir>
        </params>

        <operator-list>
                <operator name="Opr 1">
                        <preferred-language>en</preferred-language>
                        <database>MSSQL</database>
                </operator>
                <operator name="Opr 2">
                        <preferred-language>fr</preferred-language>
                        <database>Oracle</database>
                </operator>
        </operator-list>

</config>
I first parsed the entire document and then used
XPathAPI.selectNodeIterator(Document, xpath) method to get values like xxx
by using xpath : /config/params/configDir/text()
Then I have extracted the node operator from the file. Now I need to extract
<database> values from that by giving the path relative to the operator
node. I am giving this part
of  code below:
        NodeList nl = null;
        nl = doc.getOprNodesFromDoc();
        int size = nl.getLength();
        System.out.println("Size " +size);------------------> number of
<operator> nodes.
        for(int i = 0; i < size; ++i) {
            Node opr = nl.item(i);
            str = XPathAPI.selectNodeIterator(opr,
xpath);--------------------> What should be the xpath here if it is relative
to the operator node.
        }
Using xpath operator/database/text() is not working. And I do not want to
use the full path starting from /config.
Any help would be appreciated.
Thanks and Regards,
Kakoli
