try this. will stop after first node selection.
public NodeList getXpathNodeList(String p_node_path) {
p_node_path += "/[0]";
try {
return (org.apache.xpath.XPathAPI.selectNodeList(xmldoc, p_node
_path));
} catch (TransformerException e) {
e.printStackTrace();
return null;
}

Subject: XML Parser : Select first node from DOM corresponding to xpath
Hi All,
I am new to XML Parsing. I am using xerces ( DOM ) parser and using
following function to get the nodelist:
public NodeList getXpathNodeList(String p_node_path) {
try {
return (org.apache.xpath.XPathAPI.selectNodeList(xmldoc, p_node_path));
} catch (TransformerException e) {
e.printStackTrace();
return null;
}
}
selectNodeList() is taking 90% of transactions time.
PackagesMethod NameCallsCumulative TimeMethod Time
org.apache.xpathXPathAPI.selectNodeList11331395413954
com.iflex.fcr.infra.xmlFCRJApacheXMLParser.getXpathNodeList1129138549
Question:
1. Is there any way (API available / workaround) we can stop searching the
next node after it gets first occurrence?
2. Is it logical for 1133 call XPathAPI.selectNodeList is taking 13954 ms
(DOM size is less than 6kb)?
Thanks & Regards
Subrata SEN
