XML转换为普通文本 [英] XML conversion to normal text

问题描述

我想将XML文件的内容读取到任何网页或文本文件中，这些XML文件是使用我自己创建的解析器从EDI解析它们的结果，但是，标记是无效的，因为我自己创建了它们，所以制作新标签的常规做法还是应该使用现有标签?如果是，如何读取新标签?

干杯，

Hi,

I would like to read the content of an XML file into whatever webpage or textfile, these XML files are the result of parsing them from EDI using a parser I made myself, however, the tags are not valid since I made them myself, so is it conventional to make new tags or should i be using existing tags? if yes, how can I read my new tags?

cheers,

推荐答案

请参阅我对问题的评论.标签本身不能为无效"，您的XML格式可能不正确，或者格式良好的XML可能不符合该架构，但这是一个不同的问题.您没有使用自己制作的标签来解释问题，但是通常情况下，您应该使代码有效，而不是寻求任何妥协.

但是，从XML文件中创建文本太简单了，但这是以丢失一些结构信息为代价的.最简单的方法是使用类System.Xml.XmlReader读取XML，并使用类System.IO.StreamWriter写入文本:

http://msdn.microsoft.com/en-us/library/system.xml. xmlreader.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.io. streamwriter.aspx [^ ].

如果可能是这样的话:

Please see my comments to the question. Tags themselves cannot be "invalid", your XML could be not well-formed, or well-formed XML might not comply with the schema, but this is a different issue. You did not explain your problem with tags made by yourself, but normally, you should make your code valid instead of looking for some compromise.

Nevertheless, making a text out of an XML file is way too easy, but it comes at the cost of lost some structural information. The simplest way is using the class System.Xml.XmlReader to read XML and the class System.IO.StreamWriter to write text:

http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx[^],
http://msdn.microsoft.com/en-us/library/system.io.streamwriter.aspx[^].

If could be something like this:

string XmlAttributeToText(int depth, string attributeName, string value) {
        //...
        return //... whatever you want
} //XmlAttributeToText

string XmlNodeToText(int depth, System.Xml.XmlNodeType nodeType, string name, string value) {
    //...
    return //... whatever you want
} //XmlNodeToText

string textFileName = //...
string xmlFileName = //...

using (System.IO.StreamWriter writer = new System.IO.StreamWriter(textFileName, false, System.Text.Encoding.UTF8)) {
    using (System.Xml.XmlReader reader = System.Xml.XmlReader.Create(xmlFileName)) {
        while (reader.Read()) {
            string nodeContent = XmlNodeToText(reader.Depth, reader.NodeType, reader.Name, reader.Value);
            writer.WriteLine(nodeContent); //or writer.Write, whatever is required
            if (reader.HasAttributes) {
                reader.MoveToNextAttribute();
                string attributeContent = XmlAttributeToText(reader.Depth, reader.Name, reader.Value);
                writer.WriteLine(attributeContent); //or writer.Write, whatever is required
            } //if
        } //loop
    } //using XmlReader // reader is disposed here
} //using StreamWriter // writer is disposed here, file buffer is flashed and file is closed, which is even more important

您还可以使用XML阅读器选项来忽略注释，处理指令；您可以忽略对上述循环不感兴趣的节点类型；换句话说，以适合您目标的方式来编程从XML映射到文本的映射规则.

Also you can use XML reader options to ignore comment, processing instructions; you can ignore node types you are not interested in the loop shown above; in other words — program the mapping rules for mapping from XML to text the ways suitable for your goal.
