问题描述
为什么我尝试读取XML文件的任何内容都落在根元素上？
<？xml version =1.0？>
< AnXMLTestFile xmlns：xsi =http://www.w3.org/2001/XMLSchema-instancexmlns：xsd =http://www.w3.org/2001/XMLSchema xmlns =un：unece：260：data：EEM：02-02-AnXMLTestFile>
/ *使用XmlReader，XmlDocument，BOM，MemoryStreamer / Writer ，...
即使我省略了'编码GetEncoding（）'方法，我仍然在路径'中有' 非法字符代码行
Why is anything that I try to read out the XML file is falling over the root element?
<?xml version="1.0"?>
<AnXMLTestFile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="un:unece:260:data:EEM:02-02-AnXMLTestFile">
/* Using XmlReader, XmlDocument, BOM, MemoryStreamer/Writer, ...
Even if I leave out the method 'Encoding GetEncoding()' I still have the 'illegal characters in path' on codeline
XmlTextReader reader = new XmlTextReader(doc.ToString());
* /
改进 ：
清理了一些代码，只是为了使用基础知识。将字符串更改为使用
*/
Improvement:
cleaned up some code just to use the basics. changed the string to use
string xml = richTextBox1.Text;
现在代码没有遍历我的nodeList。
有人可以帮帮我吗？在此先感谢。
我尝试过：
XML-文件示例
Now the code doesn't loop over my nodeList.
Can somebody help me please? Thanks in advance.
