Examples of org.apache.xmlbeans.XmlObject.selectPath()

org.apache.xmlbeans.XmlObject.selectPath()
ri.org/sample"> <element name="owner" type="person"/> <complexType name="person"> [...] </complexType> </schema> and suppose "owner" tags can be scattered throughout the document. Then we can write the following code to find them all:
```
 import org.openuri.sample.Person; import org.apache.xmlbeans.*; [...] XmlObject xobj = XmlObject.Factory.parse(myFile); Person[] results; results = (Person[])xobj.selectPath( "declare namespace s='http://www.openuri.org/sample' " + ".//s:owner"); 
```
Notice the way in which namespace declarations are done in XPath 2.0. Since XPath can only navigate within an XML document - it cannot construct new XML - the resulting XmlObjects all reside in the same XML document as this XmlObject itself.

    protected void read(InputStream is) throws IOException, XmlException {
        XmlObject root = XmlObject.Factory.parse(is);


        _qnames = new ArrayList<QName>();
        _items = new ArrayList<XmlObject>();
        for(XmlObject obj : root.selectPath("$this/xml/*")) {
            Node nd = obj.getDomNode();
            QName qname = new QName(nd.getNamespaceURI(), nd.getLocalName());
            if (qname.equals(QNAME_SHAPE_LAYOUT)) {
                _items.add(CTShapeLayout.Factory.parse(obj.xmlText()));
            } else if (qname.equals(QNAME_SHAPE_TYPE)) {
