我最近完成了一个关于几个 jsFiddles 的教程并解释了如何使用YQL, XPATH和 jQuery.ajax()对于一个不同的 SO 问题，这将为您指明方向。你可以看到所以在这里回答 https://stackoverflow.com/a/14042902/1195891.
为了让您的问题得到可接受的答案，我制作了一个工作演示，向您展示从您请求的网页中抓取数据是多么容易。
jsFiddle 演示包含大量评论和console.log()消息以了解工作流程。确保您激活浏览器控制台并使用Firebug http://getfirebug.com/enable例如。这HTML and CSS用于构造教职员工信箱模仿原始网站中的链接，包括图像、名称、电子邮件和网页主题中的链接。

修改！！！ 另外修改了上面的jsFiddle，参见相关
jsFiddle 教程：创建动态 Div 的 (现在改进了！) http://jsfiddle.net/C5xWL/1/
HTML:
<div id="results"></div>
jQuery:
var directoryName = 'child-development-program';
$.ajax({
type: 'GET',
url: "http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22http%3A%2F%2Fdirectory.vancouver.wsu.edu%2F" + directoryName + "%22%20and%20xpath%3D%22%2F%2Fdiv%5B%40id%3D'content-inner'%5D%2Fdiv%2Fdiv%2Fdiv%2Fdiv%2Fdiv%5B2%5D%22",
dataType: 'xml',
success: function(data) {
if (data) {
// Show in console the jQuery Object.
console.info('Here is the returned query');
console.log( $(data).find('query') );
// Show in console the results in inner-html text.
var textResults = $(data).find('results').text();
console.log( textResults );
// Parse the list of faculty members. Variable indexFM is not used for indexed faculty member.
$(data).find('results').find('.views-row').each(function(indexFM){
// This variable will store the current faculty member.
var facultyMember = this;
console.info('Faculty jQuery DIV Object shown on next lines.');
console.log( facultyMember );
// Parse the contents of each faculty member. Variable indexFC is not used for indexed faculty content.
$(facultyMember).each(function(indexFC){
// Get Thumbnail Image of Faculty Member
var facultyMemberImage = $(this).find('.views-field-field-profile-image-fid #directoryimage a img').attr('src');
console.log( facultyMemberImage );
// Get Title (Name) of Faculty Member
var facultyMemberTitle = $(this).find('.views-field-field-professional-title-value #largetitle').text();
console.log( facultyMemberTitle );
// Get relative URL fragment.
//
// Stackoverflow Edit: Much more extraction in this section, see jsFiddle link above.
//
// Get Email of Faculty Member
var facultyMemberEmail = $(this).find('.views-field-field-email-value span').text();
// Simple dashed line to separate faculty members as seen in browser console.
console.log('--------');
var divObject = '<div class="dynamicResults"><div class="dynamicThumb"><a href="' + facultyMemberUrl + '"><img src="' + facultyMemberImage + '" alt=""></a></div><div class="dynamicInfo"><div class="dynamicText"><a href="' + facultyMemberUrl + '" class="dynamicName">' + facultyMemberTitle + '</a></div><div class="dynamicText">' + facultyMemberPosition + '</div><div class="dynamicText">Phone: ' + facultyMemberPhone + '</div><div class="dynamicText">Location: ' + facultyMemberBuilding + ' <span>' + facultyMemberRoom + '</span></div><div class="dynamicText"><a href="' + facultyMemberEmailUrl + '" class="dynamicEmail">' + facultyMemberEmail + '</a><span class="dynamicEmailpic"></span></div></div></div><div class="clear"></div>';
// Build webpage with dynamic data.
$('#results').append( divObject );
});
});
}
}
});

但在真正考虑你的问题时，我想尝试一些新的、简单的东西......但是结果是非常可以接受的。这次，数据抓取技术使用的是网页原生CSS文件作为 jsFiddle 中的资产，同时也将返回的数据直接使用到DOM.
该方法使用与上面相同的原理，不同之处在于它使用html as the .ajax() dataType有可用的近乎克隆的原始网页。唯一的缺点是需要整个 CSS 文件，但您可以解析原始文件以删除不需要的多余样式和选择器（重要的是不要打破 IE 中的 4096 CSS 选择器障碍).
