我需要能够从中获取图像。我想知道最好的方法是什么?我可以搜索正则表达式吗?另外关于 … 等有没有办法轻松转换这些?所有帮助表示赞赏。下面是我当前获取提要并循环通过它的代码,我的目标是将我的数据数组的 leftImage 元素设置为内容编码标签内的图像。
var url="http://www.highlandradio.com/feed/";
//rss feed url
var xhr = Titanium.Network.createHTTPClient();
xhr.onload = function() {
// Data is returned from the blog, start parsing
var doc = this.responseXML.documentElement;
// begin looping through blog posts
var items = doc.getElementsByTagName("item");
console.log(items);
for (var i=0;i<items.length;i++) {
data.push({
title: "'"+items.item(i).getElementsByTagName("title").item(0).text+"'",
leftImage:'NewsStory.png',
dataToPass: "'"+items.item(i).getElementsByTagName("description").item(0).text+"'",
className: "TableRow",
hasChild: true,
jsTest: true,
js:"external.js"
});
}
};
