android - 如何将字符串转换为文档对象

Question

我有一个包含 xml 内容的字符串，如下所示:

String xml = "<item_list>" +
                "<category id='2' name='categoryName'>" +
                   "<item id='41' name='item1' />" +
                "</category>" +
             "</item_list>)";

我想将其转换为文档对象。这是我执行此操作的代码:

Document doc = null;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
StringReader sr = new StringReader(xml);
InputSource is = new InputSource(sr);
doc = builder.parse(is);

当我运行它时，我得到了下一个错误:

org.xml.sax.SAXParseException: Unexpected token (position:TEXT )@1:139 in java.io.InputStreamReader@40fa7860)

我做错了什么？

将您的 xml 字符串更改为:

String xml = "<?xml version='1.0' encoding='UTF-8'?>" +
                "<item_list>" +
                "<category id='2' name='categoryName'>" +
                   "<item id='41' name='item1' />" +
                "</category>" +
             "</item_list>";

目前您缺少 xml 文档标题 <?xml version='1.0' encoding='UTF-8'?>在你的字符串中
