[英]get grandson text using xml document in c#
I'm using XmlDocument in C# and I would like to know how to get grandson data of the root? 我在C#中使用XmlDocument,我想知道如何获取根的孙子数据?
<tRoot>
<One>
<a>15</a>
<b>11</b>
<c>1</c>
<d>11.35</d>
<e>0</e>
<f>289</f>
</One>
<Two>
<a>0</a>
<b>11</b>
<c>1</c>
<d>0.28</d>
<e>0</e>
<f>464</f>
</Two>
</tRoot>
and I want the ability to get a of One and also a of Two 而且我想要获得一个“一个”和“两个”的能力
I tried: 我试过了:
var doc = new XmlDocument();
doc.Load(Consts.FileConst);
var docXml = doc["One"];
if (docXml != null)
{
float valFromXml = float.Parse(docXml["a"].InnerText);
}
The issue is that docXml is null 问题是docXml为空
Any assitance? 有什么帮助吗?
Try this: 尝试这个:
XmlDocument d = new XmlDocument();
d.LoadXml("<tRoot><One><a>15</a><b>11</b><c>1</c><d>11.35</d><e>0</e><f>289</f></One><Two><a>0</a><b>11</b><c>1</c><d>0.28</d><e>0</e><f>464</f></Two></tRoot>");
XmlNodeList itemNodes = d.SelectNodes("//*/a");
As suggested above, XDocument would be a better alternative. 如上所述,XDocument将是更好的选择。 If, however, you still want to use XmlDocument, you can iterate through the children using 但是,如果仍然要使用XmlDocument,则可以使用以下命令遍历子级
var doc = new XmlDocument();
doc.Load(Consts.FileConst);
foreach(XmlNode xmlNode in doc.DocumentElement.ChildNodes) {
//access a/b/c/d/e using:
xmlNode.ChildNodes[0].InnerText; //for a
xmlNode.ChildNodes[1].InnerText; //for b
}
