I´m trying to parse a xml but getting a error.

public static String xmlVersion(String source) {

try {
    DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
    Document document = documentBuilder.parse(source);
    return document.getDocumentElement().getAttribute("versao");
} catch (SAXException | IOException | ParserConfigurationException e) {
    e.printStackTrace();
}
return null;

}

And the stackTrace

您使用的方法DocumentBuilder#parse(String)需要 XML 源的 URI（例如文件或 HTTP URI），它保存 XML 内容，而不是 XML 内容本身。

如果您真的想将您的 XML 内容作为 aString传递，请考虑将InputSource环绕 a 的传递StringReader给DocumentBuilder#parse(InputSource)：

documentBuilder.parse(new InputSource(new StringReader(source)));
