首页在VS2010 中新建一个WEBservice程序，

源码如下：

using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Collections.Generic; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Linq; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Web; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Web.Services; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Xml; using Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Xml.XPath; /// <summary> ///WebService 的<a href="/tag/zhaiyao/" target="_blank" class="keywords">摘要</a>说明 /// </summary> [WebService(Namespace = "http://te<a href="/tag/mpu/" target="_blank" class="keywords">mpu</a>ri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] //若要允许使用 ASP.NET AJAX 从脚本中<a href="/tag/diaoyong/" target="_blank" class="keywords">调用</a>此 Web 服务，请取消对下行的注释。 // [Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Web.Script.Services.ScriptService] public class WebService : Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.Web.Services.WebService { public WebService () { //如果使用设计的组件，请取消注释以下行 //InitializeComponent(); } [WebMethod] public string HelloWorld() { return "Hello World"; } [WebMethod] public string GetXMLByXpath(string xpaths) { XPathDocument xmldoc = new XPathDocument(Server.MapPath("books.xml")); XPathNavigator xpathnav = xmldoc.CreateNavigator(); XPathNodeI<a href="/tag/tera/" target="_blank" class="keywords">tera</a>tor result; result = xpathnav.Select(xpaths); string ss=""; while (result.MoveNext()) { ss += result.Current.InnerXml; //ss += "< br />"; } if (ss.Length<1) return "没有符号要求的结果"; else return ss; } }

在新建一个html文件

源码：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <mce:script src="Scripts/jquery-1.4.1-vsdoc.js" mce_src="Scripts/jquery-1.4.1-vsdoc.js" type="text/javascript"></mce:script> <mce:script type="text/javascript"></mce:script> </head> <body> <div style="border: thin solid #0000FF; float:left; <a href="/tag/dis/" target="_blank" class="keywords">dis</a>play:block; width:55%; height:100%; "> <div id="commandarea"> <input id="xpathcommand" type="text" value="input" /> <input type="button" id="sent" value="sent" /> </div> <div id="result"> </div></div> <div style="border: thin solid #0000FF; width:40%; float:left;height:100%;"> <iframe src="books.xml" mce_src="books.xml" width="100%"; height="550px";scrolling="auto" /> </div> </body> </html>

books.xml 代码，

<?xml version="1.0" encoding="ISO-8859-1"?> <bookstore> <book category="COOKING"> <title lang="en">Everyday Italian</title> <author>Giada De Laurentiis</author> <year>2005</year> <price>30.00</price> </book> <book category="CHILDREN"> <title lang="eng">Harry P<a href="/tag/ott/" target="_blank" class="keywords">ott</a>er</title> <author>J K.
