零散的XML字符串使用LINQ解析 [英] Fragmented XML string parsing with Linq

问题描述

让我们说我有一个支离破碎的XML如下：

Let's say I have a fragmented XML as follows.

<A>
  <B></B>
</A>
<A>
  <B></B>
</A>

我可以使用的XmlReader 与片段选项来解析该未完成 XML字符串。

I can use XmlReader with Fragment option to parse this not complete XML string.

XmlReaderSettings settings = new XmlReaderSettings();
settings.ConformanceLevel = ConformanceLevel.Fragment;
XmlReader reader;
using (StringReader stringReader = new StringReader(inputXml))
{
    reader = XmlReader.Create(stringReader, settings);
}
XPathDocument xPathDoc = new XPathDocument(reader);
XPathNavigator rootNode = xPathDoc.CreateNavigator();
XPathNodeIterator pipeUnits = rootNode.SelectChildren("A", string.Empty);
while (pipeUnits.MoveNext())

我能做到这一点支离破碎的XML字符串使用LINQ解析？

Can I do this fragmented XML string parsing with Linq?

推荐答案

使用<一个href="http://msdn.microsoft.com/en-us/library/system.xml.linq.xnode.readfrom.aspx"><$c$c>XNode.ReadFrom()方法，你可以很容易地创建一个返回 XNode S的序列的方法：

Using the XNode.ReadFrom() method, you can easily create a method that returns a sequence of XNodes:

public static IEnumerable<XNode> ParseXml(string xml)
{
    var settings = new XmlReaderSettings
    {
        ConformanceLevel = ConformanceLevel.Fragment,
        IgnoreWhitespace = true
    };

    using (var stringReader = new StringReader(xml))
    using (var xmlReader = XmlReader.Create(stringReader, settings))
    {
        xmlReader.MoveToContent();
        while (xmlReader.ReadState != ReadState.EndOfFile)
        {
            yield return XNode.ReadFrom(xmlReader);
        }
    }
}
