尝试使用以下代码解析 res/xml 中的 xml 文件。但是当启动项目时，它显示异常“没有这样的文件/目录”。代码中是否有任何错误？立即给我一个答案。在此先感谢。

 try
    {
        DocumentBuilderFactory docBuilderFactory=DocumentBuilderFactory.newInstance();
        DocumentBuilder docBuilder=docBuilderFactory.newDocumentBuilder();
        *Document doc=docBuilder.parse(new File("project_data.xml"));*
        NodeList projects=doc.getElementsByTagName("PROJECTDESC");
        for(int i=0;i<projects.getLength();i++)
        {
            Element project=(Element)projects.item(i);
            ProjectData projectdata=new ProjectData(null, null, null, null, null, null);

            projectdatas.add(projectdata);
            projectdata.setProject(project.getFirstChild().getNodeValue());
            projectdata.getProject();
        }
    }
catch (Throwable t) {
        Toast.makeText(this, "Request failed: "+t.toString(), 4000).show();
    }

XML 文件是

<?xml version="1.0" encoding="ISO-8859-1"?>

如果它给您的异常是“没有这样的文件/目录”，那么您的错误在于project_data.xml文件的位置/名称。查看此资源以获取有关 Android 中文件存储的更多信息……您的 xml 文件可能不在您期望的位置。

创建您的res\raw xml 文件，然后使用：

Resources res = getResources();

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

DocumentBuilder db = dbf.newDocumentBuilder();

InputStream is = res.openRawResource(R.raw.file);

Document doc=db.parse(new InputSource(is));
