我正在尝试从 BBC RSS 提要中读取 XML 数据，并且已成功读取数据，但是，新闻报道显示的次数过多。我希望每个故事都显示在自己的容器中(即 div 元素)。相反，它会在 46 个容器中的每一个容器中显示所有新闻故事(目前有 46 个故事)。

非常感谢任何帮助。
编辑 以下是后端脚本的代码:newsStore.php。
<?php
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control: max-age=0");
header("Content-Type: text/xml");
?>
<?php
function get_url_contents($url){
$crl = curl_init();
$timeout = 5;
curl_setopt ($crl, CURLOPT_URL,$url);
curl_setopt ($crl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($crl, CURLOPT_CONNECTTIMEOUT, $timeout);
$ret = curl_exec($crl);
curl_close($crl);
return $ret;
}
$url = "http://feeds.bbci.co.uk/news/rss.xml?edition=int#";
$str = file_get_contents($url);
echo $str;
?>
最佳答案
回调传递给.each()可以接受两个参数
Type: Function( Integer indexInArray, Object value ).
因此回调可以利用代表每个 <item> 的对象值节点。将项目对象传递给 $() 后, 调用 .find()获取标题(然后是标题节点的文本)。
$(xml).find('item').each(function(index, item) {
var item_title = $(item).find("title").text();
请参阅下面的实际操作。
注意:因为 AJAX 在这里不起作用，除非我们让 php 脚本在同一个域中工作，所以我更改了 $.ajax()出于演示目的 - 我不建议定期这样做。另外 - 我将提要数据缩减为几个结果
$(document).ready(function() {
$.ajax({
type: "GET",
url: "newsStore.php",
cache: false,
dataType: "xml",
jsonp: "callback",
success: parse_rss
});
});
function parse_rss(xml) {
//get feed
$(xml).find('item').each(function(index, item) {
var item_title = $(item).find("title").text();
//var image_url = $(xml).find("thumbnail").last().attr("url");
//$('#title_div').append(item_title);
//adding all titles to each title_div atm
$("#title_div").append('<p>' + item_title + '</p>');
});
}
$.ajax = function(params) {

我正在学习如何使用Nokogiri，根据这段代码我遇到了一些问题:require'rubygems'require'mechanize'post_agent=WWW::Mechanize.newpost_page=post_agent.get('http://www.vbulletin.org/forum/showthread.php?t=230708')puts"\nabsolutepathwithtbodygivesnil"putspost_page.parser.xpath('/html/body/div/div/div/div/div/table/tbody/tr/td/div
我有一个Ruby程序，它使用rubyzip压缩XML文件的目录树。gem。我的问题是文件开始变得很重，我想提高压缩级别，因为压缩时间不是问题。我在rubyzipdocumentation中找不到一种为创建的ZIP文件指定压缩级别的方法。有人知道如何更改此设置吗？是否有另一个允许指定压缩级别的Ruby库？ 最佳答案 这是我通过查看rubyzip内部创建的代码。level=Zlib::BEST_COMPRESSIONZip::ZipOutputStream.open(zip_file)do|zip|Dir.glob("**/*")d

很好奇，就使用rubyonrails自动化单元测试而言，你们正在做什么？您是否创建了一个脚本来在cron中运行rake作业并将结果邮寄给您？git中的预提交Hook？只是手动调用？我完全理解测试，但想知道在错误发生之前捕获错误的最佳实践是什么。让我们理所当然地认为测试本身是完美无缺的，并且可以正常工作。下一步是什么以确保他们在正确的时间将可能有害的结果传达给您？ 最佳答案 不确定您到底想听什么，但是有几个级别的自动代码库控制:在处理某项功能时，您可以使用类似autotest的内容获得关于哪些有效，哪些无效的即时反馈。要确保您的提
假设我做了一个模块如下:m=Module.newdoclassCendend三个问题:除了对m的引用之外，还有什么方法可以访问C和m中的其他内容？我可以在创建匿名模块后为其命名吗(就像我输入“module...”一样)？如何在使用完匿名模块后将其删除，使其定义的常量不再存在？ 最佳答案 三个答案:是的，使用ObjectSpace.此代码使c引用你的类(class)C不引用m:c=nilObjectSpace.each_object{|obj|c=objif(Class===objandobj.name=~/::C$/)}当然这取决于

关闭。这个问题是opinion-based.它目前不接受答案。想要改进这个问题？更新问题，以便editingthispost可以用事实和引用来回答它.关闭4年前。Improvethisquestion我想在固定时间创建一系列低音和高音调的哔哔声。例如:在150毫秒时发出高音调的蜂鸣声在151毫秒时发出低音调的蜂鸣声200毫秒时发出低音调的蜂鸣声250毫秒的高音调蜂鸣声有没有办法在Ruby或Python中做到这一点？我真的不在乎输出编码是什么(.wav、.mp3、.ogg等等)，但我确实想创建一个输出文件。
我在我的项目目录中完成了compasscreate.和compassinitrails。几个问题:我已将我的.sass文件放在public/stylesheets中。这是放置它们的正确位置吗？当我运行compasswatch时，它不会自动编译这些.sass文件。我必须手动指定文件:compasswatchpublic/stylesheets/myfile.sass等。如何让它自动运行？文件ie.css、print.css和screen.css已放在stylesheets/compiled。如何在编译后不让它们重新出现的情况下删除它们？我自己编译的.sass文件编译成compiled/t
我想将html转换为纯文本。不过，我不想只删除标签，我想智能地保留尽可能多的格式。为插入换行符标签，检测段落并格式化它们等。输入非常简单，通常是格式良好的html(不是整个文档，只是一堆内容，通常没有anchor或图像)。我可以将几个正则表达式放在一起，让我达到80%，但我认为可能有一些现有的解决方案更智能。 最佳答案 首先，不要尝试为此使用正则表达式。很有可能你会想出一个脆弱/脆弱的解决方案，它会随着HTML的变化而崩溃，或者很难管理和维护。您可以使用Nokogiri快速解析HTML并提取文本:require'nokogiri'h
