Converts a string to xml and obtains the corresponding value.

Converts a string to xml and obtains the corresponding value.

For example, a field in the database stores a string in xml format:

<? Xml version = "1.0" encoding = "UTF-16"?>
<ArrayOfPassengerInfoForXml xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" xmlns: xsd = "http://www.w3.org/2001/XMLSchema">
<PassengerInfoForXml>
<Person> 1 </Person>
<Name> Zhang San </Name>
<InsureNumber> 2 </InsureNumber>
</PassengerInfoForXml>
<PassengerInfoForXml>
<Person> 1 </Person>
<Name> Li Si </Name>
<InsureNumber> 1 </InsureNumber>
</PassengerInfoForXml>
</ArrayOfPassengerInfoForXml>

 

Method 1: js

// Convert the string to xmlfunction toXmlDom (source) {var xmlDoc = null; if (window. activeXObject) {var ARR_ACTIVEX = ["MSXML4.DOMDocument", "MSXML3.DOMDocument", "MSXML2.DOMDocument", "MSXML. DOMDocument "," Microsoft. xmlDom "]; var XmlDomflag = false; for (var I = 0; I <ARR_ACTIVEX.length &&! XmlDomflag; I ++) {try {var objXML = new ActiveXObject (ARR_ACTIVEX [I]); xmlDoc = objXML; XmlDomflag = true;} catch (e) {}} if (xmlDoc) {xmlDoc. async = false; xmlDoc. loadXML (source) ;}} else {var parser = new DOMParser (); var xmlDoc = parser. parseFromString (source, "text/xml");} return xmlDoc ;}

 

Function getXmlDom (source) {var strXML = ""; // strXML is the above xml Format String var s = toXmlDom (strXML); $ (s ). find ("PassengerInfoForXml "). each (// obtain each signature function (id, item) {// obtain the TAG content var Person =$ (item ). find ("Person "). eq (0 ). text (); var Name = $ (item ). find ("Name "). eq (0 ). text (); var InsureNumber = $ (item ). find ("InsureNumber "). eq (0 ). text (); alert (Name );});}

 

Method 2: asp.net background

1) create a class PassengerInfoForXml. cs that corresponds to the fields of each tag.

using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace WebApplication1{    public class PassengerInfoForXml    {        public Int32 Person { get; set; }        public String Name { get; set; }        public Int32 InsureNumber { get; set; }    }}

2) obtain the value of each tag

Protected List <PassengerInfoForXml> passengerlist = null; string strxml = ""; // The preceding xml Format string protected void button#click (object sender, EventArgs e) {passengerlist = ConvertToObject (strxml, typeof (List <PassengerInfoForXml>) as List <PassengerInfoForXml>; for (int I = 0; I <passengerlist. count; I ++) {var Person = passengerlist [I]. person; var Name = passengerlist [I]. name; var InsureNumber = passengerlist [I]. insureNumber; Response. write ("<script> alert ('" + Name + "') </script>");} // convert to the object PassengerInfoForXml public static object ConvertToObject (string xml, type objectType) {object obj2 = null; if (string. isNullOrEmpty (xml) {return obj2;} using (StringReader reader = new StringReader (xml) {XmlSerializer serializer = new XmlSerializer (objectType); return serializer. deserialize (reader );}}
