Chcę CONFIDENTIAL jak mój pożądany wynik.

Zgodnie z XPath, mój problem został rozwiązany.

final var xpathFilter = "*//v:shape/v:textpath/@string"

declare namespace to może być wykonane w XQuery, ale nie w XPath, więc albo użyj procesor XQuery, taka jak BaseX lub Saxon 10 lub 9, albo przeczytać API wybranego procesora XPath, dla XPath zwykle jest to metoda API do wiązania prefiksów do URI przestrzeni nazw, aby można było używać przedrostków w wyrażeniach XPath.

XMLBeans domyślnie nie obsługuje złożone XPath, w tym data() filtry metod i predykatów, itp. Do obsługi tych funkcji opiera się na Saxon uczestniczyć w drodze do klasy.

Dla XMLBeans 3.x.x trzeba będzie ręcznie pobrać Saxon 9.0.0.4 j i dodaj go w drogę do klasy

Dla XMLBeans 5.x.x (najnowsza wersja) potrzebujemy Saxon-HE 10.x który możemy możemy bezpośrednio dodać do naszego pliku pom w następujący sposób

<dependencies>
    <dependency>
        <groupId>org.apache.xmlbeans</groupId>
        <artifactId>xmlbeans</artifactId>
        <version>5.0.1</version>

    </dependency>
    <dependency>
        <groupId>net.sf.saxon</groupId>
        <artifactId>Saxon-HE</artifactId>
        <version>10.6</version>
    </dependency>
</dependencies>

Po drugie, trzeba będzie wymienić - ręcznie lub w kodzie przed badaniem-korzeń <xml-fragment> rozpoczynający się i kończący się tag z inną nazwą znacznika, np. <root> bo w przeciwnym razie XMLBeans analizuje go jak document fragment będąc typem schematu węzła głównego zamiast document typ i XPath z предикатами nie będą działać.

W końcu, zakładając, że dodaliśmy Saxona i załatwić z <xml-fragment/> etykieta. Aby uzyskać CONFIDENTIAL wartość jako wyjścia, tylko musimy doprowadzić wynik do SimpleValue i zadzwoń getStringValue()na nim.

Oto zmodyfikowany

import org.apache.xmlbeans.SimpleValue;
import org.apache.xmlbeans.XmlException;
import org.apache.xmlbeans.XmlObject;
import java.io.File;
import java.io.IOException;

public class main {
    public static void main(String[] args) {
        File file = new File("test.xml");
        try {
            XmlObject xoobj = XmlObject.Factory.parse(file);
            var declareNameSpaces = "declare namespace v='urn:schemas-microsoft-com:vml' ";
            final String xpathFilter = "data(//v:shape[contains(@id,'PowerPlusWaterMarkObject')]/v:textpath/@string)";

            XmlObject[] arr = xoobj.selectPath(declareNameSpaces + xpathFilter);
            
            //Cast to SimpleValue
            SimpleValue result = (SimpleValue) arr[0];
            System.out.println(result.getStringValue());

        } catch (XmlException | IOException ex) {
            System.out.println(ex);
        }
    }
