* Document-class: LibXML::XML::XPath
3-
*
4-
* The XML::XPath module is used to query XML documents. It is
5-
* usually accessed via the XML::Document#find or
6-
* XML::Node#find methods. For example:
7-
*
8-
* document.find('/foo', namespaces) -> XML::XPath::Object
9-
*
10-
* The optional namespaces parameter can be a string, array or
11-
* hash table.
12-
*
13-
* document.find('/foo', 'xlink:http://www.w3.org/1999/xlink')
14-
* document.find('/foo', ['xlink:http://www.w3.org/1999/xlink',
15-
* 'xi:http://www.w3.org/2001/XInclude')
16-
* document.find('/foo', 'xlink' => 'http://www.w3.org/1999/xlink',
17-
* 'xi' => 'http://www.w3.org/2001/XInclude')

* === Working With Default Namespaces
21-
*
22-
* Finding namespaced elements and attributes can be tricky.
23-
* Lets work through an example of a document with a default
24-
* namespace:
25-
*
26-
* <?xml version="1.0" encoding="utf-8"?>
27-
* <feed xmlns="http://www.w3.org/2005/Atom">
28-
* <title type="text">Phil Bogle's Contacts</title>
29-
* </feed>
30-
*
31-
* To find nodes you must define the atom namespace for
32-
* libxml. One way to do this is:
33-
*
34-
* node = doc.find('atom:title', 'atom:http://www.w3.org/2005/Atom')
35-
*
36-
* Alternatively, you can register the default namespace like this:
37-
*
38-
* doc.root.namespaces.default_prefix = 'atom'
39-
* node = doc.find('atom:title')
40-
*
41-
* === More Complex Namespace Examples
42-
*
43-
* Lets work through some more complex examples using the
44-
* following xml document:
45-
*
46-
* <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
47-
* <soap:Body>
48-
* <getManufacturerNamesResponse xmlns="http://services.somewhere.com">
49-
* <IDAndNameList xmlns="http://services.somewhere.com">
50-
* <ns1:IdAndName xmlns:ns1="http://domain.somewhere.com"/>
51-
* </IDAndNameList>
52-
* </getManufacturerNamesResponse>
53-
* </soap:Body>
54-
* </soap:Envelope>
55-
*
56-
* # Since the soap namespace is defined on the root
57-
* # node we can directly use it.
58-
* doc.find('/soap:Envelope')
59-
*
60-
* # Since the ns1 namespace is not defined on the root node
61-
* # we have to first register it with the xpath engine.
62-
* doc.find('//ns1:IdAndName',
63-
* 'ns1:http://domain.somewhere.com')
64-
*
65-
* # Since the getManufacturerNamesResponse element uses a default
66-
* # namespace we first have to give it a prefix and register
67-
* # it with the xpath engine.
68-
* doc.find('//ns:getManufacturerNamesResponse',
69-
* 'ns:http://services.somewhere.com')
70-
*
71-
* # Here is an example showing a complex namespace aware
72-
* # xpath expression.
73-
* doc.find('/soap:Envelope/soap:Body/ns0:getManufacturerNamesResponse/ns0:IDAndNameList/ns1:IdAndName',
74-
* ['ns0:http://services.somewhere.com', 'ns1:http://domain.somewhere.com'])
