Question

解析代码是：

private UrlList parseUrl(URL url) {
    URL SourceUrl = null;
    SourceUrl = url;

    try {
        /** Handling XML */
        SAXParserFactory spf = SAXParserFactory.newInstance();
        SAXParser sp = spf.newSAXParser();
        XMLReader xr = sp.getXMLReader();
        /** Create handler to handle XML Tags ( extends DefaultHandler ) */
        XMLParser myXmlParser = new XMLParser();
        xr.setContentHandler(myXmlParser);
        xr.parse(new InputSource(SourceUrl.openStream()));

    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        System.out.println(" XMLParsing error is : " + e);
    }

    urlList = XMLParser.urlList;
    return urlList;
}// end of parseurl

我给的网址是 sourceUrl =新网址（“file：// C：/Users/raghu/Desktop/aero/products.xml”）; 类似地，我也以相同的方式拥有资源路径

file://C:/Users/raghu/Desktop/aero/"resource sub folders"

我收到以下错误

Answer 1

您需要将文件推送到Android模拟器文件系统。例如

adb push C:/Users/raghu/Desktop/aero/products.xml /sdcard/products.xml

并使用后一条路径。

我正在尝试解析桌面上的xml文件。我收到了一个错误
