If anyone stumbles upon this via a search engine, I fixed my problem.
XPath uses InputSources to parse expressions, but it can also use Document objects. You can use a loader like:
[java]
public class XMLLoader implements AssetLoader {
public Document load(AssetInfo assetInfo) {
return createDocFromStream(assetInfo.openStream());
}
public static Document createDocFromStream(InputStream inputStream) {
try {
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
return builder.parse(inputStream);
} catch (Exception ex) {
return null;
}
}
}
[/java]
to create a Document object from your XML file. You will need to call:
[java] assetManager.registerLoader(XMLLoader.class, “ext”) [/java]
to register your loader. You can then grab your XML file and evaluate XPath expressions the same way you would with an InputSource.
