如何将XML文档的值存储到c#中的字符串数组中? [英] How to store the values of an XML document into a string array in c#?

问题描述

我有一个XML文档，其属性为IP，名称和值作为位置.我想先加载XML文档，然后提取名称为attribut的内容并将其存储在字符串数组中.

我可以通过
加载文档 Doc.Load("pathname");
但是如何检索值并将其存储在字符串数组中..
请使用您的代码帮助我

I have a XML document with attributes IP and Name and Value as Location. I want to load the XML document first and then extract the contents under name attribut and store it in a string array.

I can load the document by
Doc.Load("pathname");
but how to retrieve the values and store in a string array..
pls help me with ur code

推荐答案

Shaheen，

在下面的代码中，我使用了二维数组，并且可以使用

Shaheen,

In the below code I used a double dimensional array, and the name can be get by using

attributes.item[1].Value.ToString();

.

as you are using the XmlNode.Attributes property to get the attributes collection.

file.Load("C:\\Users\\shaheen.n\\Documents\\LocationFile.xml");
XmlNodeList tree = file.GetElementsByTagName("Mapping");
string[,] strarr = new string[tree.Count,3];

foreach (XmlNode node in tree)
{
    XmlAttributeCollection attributes = node.Attributes;
    ip = attributes.item[0].Value.ToString();
    name = attributes.item[1].Value.ToString();
    location = node.ChildNodes[0].Value.ToString();

    // use the code to add to you string array, if you are using the double dimensional array, like -
    strarr[ind,0] = ip;
    strarr[ind,1] = name;
    strarr[ind,2] = location;
    ind++;
}

for(int i =0;i<strarr.length;i++)
{
    if(strarr[0]==ip)
    {
        Console.WriteLine("LOCATION corresponding to the entered IP is : {0}",strarr[ind,2]);
        Console.WriteLine("NAME corresponding to the entered IP is : {0}",strarr[ind,1]);
    }
}

使用Linq转换为Xml(using System.Xlm.Linq;).然后，您可以像这样进行整理(您可能需要对其进行一些微调，但是您明白了):

Use Linq to Xml (using System.Xlm.Linq;). Then you can do somnething like this (you may need to tweak it a little, but you get the point):

XDocument = XDocument.Load(filename)
XElement root = xDocument.Element("IPLocation");
IEnumerable<XElement> list = root.Elements(); 
foreach (XElement element in list) 
{
    string ipAddr = element.Attribute("ip").Value;
    string location = element.Element("Mapping").Value;
}

涉及的代码更少...

Much less code involved...

尝试一下-

Try this -

TextReader r = new StreamReader(pathname);
while ((i=r.ReadLine())!=null)
{
strXML += i;
}
