xpathAPI- selecting the parent node

[asd]

Hi all,

My XML file is as shown below:

<?xml version="1.0" ?>
<messages>
<message>
<code>100</code>
<text>Unknown application error</text>
</message>
</messages>

My java code:

Element root_element = msg_doc.getDocumentElement();
String xpath_query = "/messages/message/code/text()='100'/parent::*";

NodeList nl=XPathAPI.selectNodeList(root_element, xpath_query);

What I want to do is select the parent node of the "code" node that
contains value 100?
But the code above gives me TransformationException.

Please help me out at the earliest. Thanks in advance for all your
help.

regards,

asd

Try this (i have not tested it, though):

xPath_query = "/messages/message

";
-- Anton.

Yes, the extremely informative "ERROR! Unknown op code: 27" exception. The
string you gave isn't legal XPath, since "text()='100'' is a predicate, not
a step. That is, it chooses a subset of the current set of nodes that
match, rather than proceeding from them to another set of nodes. Predicates
are placed in square brackets. So try this, instead

/messages/message/code[text()='100']/parent::*
