How to retrieveText Node value

Question

I am generating an xml doc containing two set of data (one from ord table corresponding to orderId passed to the stored proc from calling app) and then appending child nodes for the values coming as In parameter. When I try to get the value of text node of the child element which has been appended through code, I am getting no values (I could only get to the first child value by (<xsl:value-of select="/EQUITYCONNECT//text()"/>). If I have to get the values of ORD_ID,EXECSIDE and SECURITY node in /EQUITYCONNECT/EXECRPT, how will the XPATH expression coded. (<xsl:value-of select="/EQUITYCONNECT/EXECRPT/EXECSIDE/text()"/> returns null value.
Here is the code segment

end xmlRules;
function xml_transform is taking the xml and xsl file as string and returning me xml as string after processing. Basiccally I have to do some comparison on the value of /EQUITYCONNECT/ORDER elements and /EQUITYCONNECT/EXECRPT element.
Any help will be appreciated.

Here you go:
       Node nameNode =
                (Node) XPathFactory.newInstance().newXPath().evaluate(
                        "/root/name", doc, XPathConstants.NODE);
        nameNode.setTextContent("bob");
