在将XML文件读入XmlDocument时如何忽略注释？ [英] How to ignore comments when reading a XML file into a XmlDocument?

问题描述

我想用C＃读取一个XML文档，我这样做：

I am trying to read a XML document with C#, I am doing it this way:

XmlDocument myData = new XmlDocument();
myData.Load("datafile.xml");

无论如何，我有时候在阅读XmlNode.ChildNodes时获得注释。

anyway, I sometimes get comments when reading XmlNode.ChildNodes.

对于遇到同样要求的人来说，这里是我最后做的：

For the benefit of who's experiencing the same requirement, here's how I did it at the end:

/** Validate a file, return a XmlDocument, exclude comments */
private XmlDocument LoadAndValidate( String fileName )
{
    // Create XML reader settings
    XmlReaderSettings settings = new XmlReaderSettings();
    settings.IgnoreComments = true;                         // Exclude comments
    settings.ProhibitDtd = false;                           
    settings.ValidationType = ValidationType.DTD;           // Validation

    // Create reader based on settings
    XmlReader reader = XmlReader.Create(fileName, settings);

    try {
        // Will throw exception if document is invalid
        XmlDocument document = new XmlDocument();
        document.Load(reader);
        return document;
    } catch (XmlSchemaException) {
        return null;
    }
}

谢谢

推荐答案

您可以使用 XmlReader 与 XmlReaderSettings.IgnoreComments 设置为true：

You can use an XmlReader with XmlReaderSettings.IgnoreComments set to true:

XmlReaderSettings readerSettings = new XmlReaderSettings();
readerSettings.IgnoreComments = true;
using (XmlReader reader = XmlReader.Create("input.xml", readerSettings))
{
    XmlDocument myData = new XmlDocument();
    myData.Load(reader);
    // etc...
}
