我有一个包含 xml 文件数据的字符串

如

<?xml version="1.0" encoding="UTF-8"?>

<data>

<type>
<lory>vroom</lory>
<car>crack</car>
</type>

<type>
<lory>doom</lory>
<car>chack</car>
</type>

</data>

这保存在一个名为标签的字符串中；

我使用 sax 解析器检索数据如下

SAXHelper sh = null;

            try {
                sh = new SAXHelper(newxml);
            } catch (MalformedURLException e) {
                e.printStackTrace();
            }

            sh.parseContent("");

saxhelper 类的一部分

class SAXHelper {


        public HashMap<String, String> userList = new HashMap<String, String>();
        private String data;

        public SAXHelper(String url1) throws MalformedURLException {
            this.data = new String(url1);
        }

        public RSSHandler parseContent(String parseContent) {
            RSSHandler df = new RSSHandler();
            try {

                SAXParserFactory spf = SAXParserFactory.newInstance();
                SAXParser sp = spf.newSAXParser();
                XMLReader xr = sp.getXMLReader();
                xr.setContentHandler(df);
                xr.parse(data);

            } catch (Exception e) {
                e.printStackTrace();
            }
            return df;
        }
    }

但我以这个错误结束，显示畸形错误。简而言之，我想将 xml 字符串传递给 sax 解析器以设置并获取结果。

您正在传递原始 XML：

<?xml version="1.0" encoding="UTF-

因此例外：
