Here's my SOAP response, from my web service.
I want to XmlSearch() to get the <v9:image> content.
What's the right XPath? "//v9:image" nor "//image" do not work!
回答1:
The namespace v9 isn't at the root, so you'll have to modify your syntax slightly to access elements in the v9 section of the XML doc:
<cfset results = xmlSearch(myXMLDoc,"//*[local-name()='Image' and namespace-uri()='http://fedex.com/ws/ship/v9']") />
Here, you ignore the XML declaration of v9, and explicitly refer to the namespace in the XPath search via namespace-uri(), and request the value of the element with the local-name() function.
If v9 was declared at the root (up at the top) of the XML document, the old XPath search syntax you tried using //v9:Image/ would have worked.
Due to the ColdFusion XPath library implementation, there's no way to set the namespace context arbitrarily while you perform your search; you're limited to the namespaces that are declared at the root of the document (and they are poured into the default namespace that XPath can search), thus allowing you to execute a search using namespace aliases such as //v9:Image/. This breaks when, as you get deeper into the XML, new namespaces are introduced.
SOURCE: Specify xmlns namespaces in an XPath Search
回答2:
In most XPath implementations this problem is addressed by registering the namespace URI with an arbitrary prefix in the host language, but I don't see any information related to this in the XMLSearch docs (and Google isn't much help, either).
The following work-around should help in the meantime:
//*[local-name()='Image']
This selects image elements from any (or no) namespace.
Or, more specifically (as shown in @Shawn's answer):
//*[local-name()='Image' and namespace-uri()='http://fedex.com/ws/ship/v9']
Note, however, that this would be entirely unnecessary, given some way to register the namespace with the XPath engine. For example, consider this complete Java example:
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = domFactory.newDocumentBuilder();
Document doc = builder.parse("workbook.xml");
XPath xpath = XPathFactory.newInstance().newXPath();
NamespaceContext ctx = new NamespaceContext() {
public String getNamespaceURI(String prefix) {
if ("myName".equals(prefix)) {
return "http://fedex.com/ws/ship/v9";
}
return null;
}
public String getPrefix(String uri) {
throw new UnsupportedOperationException();
}
public Iterator getPrefixes(String uri) {
throw new UnsupportedOperationException();
}
};
xpath.setNamespaceContext(ctx);
XPathExpression expr = xpath.compile("//myName:Image");
NodeList nodes = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
for (int i = 0; i < nodes.getLength(); i++) {
System.out.println("[" + nodes.item(i).getTextContent() + "]");
}
Output:
[HUGE STUFF!!!]
This code associates the prefix myName with the namespace URI http://fedex.com/ws/ship/v9. Subsequent expressions can refer to nodes in that namespace using the arbitrarily chosen prefix name:
//myName:Image
One would presume that ColdFusion supports similar functionality, but I was unable to find it in the docs. However, if such functionality does not exist, then this is a limitation of ColdFusion. In particular, it has nothing to do with XPath itself or where in the source document the namespace declaration appears.
