Quick reading of XML node content

The XML content is as follows: view code

 1 <promotion_coupons_get_response>
 2     <tot_results>
 3         200
 4     </tot_results>
 5     <coupons list="true">
 6         <coupon>
 7             <coupon_id>
 8                 123456
 9             </coupon_id>
10             <denominations>
11                 5
12             </denominations>
13             <creat_time>
14                 2000-01-01 00:00:00
15             </creat_time>
16             <end_time>
17                 2000-01-01 00:00:00
18             </end_time>
19             <condition>
20                 500
21             </condition>
22         </coupon>
23     </coupons>
24 </promotion_coupons_get_response>

Load the XML file:

Xmldocument xmldoc = new xmldocument ();

Then, you can use xmldoc. Load (...) or xmldoc. loadxml (...) to load the XML document.

After loading this XML document, we can quickly read the content in the node using the following method.

You can quickly obtain the content of an XML node by using the following methods:

View code

1 /// <summary>
2 // get the XML node Value
3 /// </Summary>
4 // <Param name = "str"> XML, for example, xmlnodelist [0]. innerxml </param>
5 // <Param name = "XPath"> node, for example, time </param>
6 /// <returns> value </returns>
7 public static string get_str_nodes (string STR, string XPath)
8 {
9 int x = 0, y = 0, Z = 0;
10 x = Str. indexof ("<" + XPath + "> ");
11 y = Str. indexof ("</" + XPath + "> ");
12 z = XPath. Length + 2;
13 if (Y> X)
14 {
15 return Str. substring (x + Z, Y-X-z). Trim ();
16}
17 else
18 {
19 Return "";
20}
21}

The above method is not explained. The specific application example is as follows:

View code

 1 XmlNodeList couponNodes = CouponXml.SelectNodes("//coupon"); 
 2               
 3             if (couponNodes != null)                
 4             {                    
 5                 foreach(XmlNode couponNode in couponNodes)                    
 6                 {                        
 7                     string coupon_Id = get_Str_Nodes(couponNode.InnerXml, "coupon_Id");                        
 8                     string denominations = get_Str_Nodes(couponNode.InnerXml, "denominations");                     
 9                 }                
10             }

You can put the method to get the node value in the common class, and it has been tested.
