HomeAway会员XML供稿常见问题

加盟XML数据Feed常见问题

入门

HomeAway提供的源是XML原子源。 XML（可扩展标记语言）是一组用于以电子方式编码文档

的规则。 XML通常用于通过Internet交换数据。因此，为了访问数据，您必须解析

提要。

以下是访问和显示xml提要的基本步骤：

第1步：获取XML Feed

步骤2：从Feed中提取或解析数据

步骤3：存储数据

步骤4：显示数据

有许多不同的方法可以从Feed中提取或解析数据。已经开发并使用了各种用于访问XML的API，

和一些已经标准化的。

拉解析器的示例包括Java编程语言中的StAX，PHP中的SimpleXML和.NET

框架中的System.Xml.XmlReader。其他受欢迎的包括：

FeedAPI - http://drupal.org/project/feedapi

SimplePie - http://simplepie.org/

PHP Universal Feed Parser -

访问数据

访问Atom提要的URL将是这样的：

https://partner.homeaway.com/aggregator/homeaway/partners/search?partnerId=cj_all&format=cjAtom&affiliateID=1。这将是

Feed的第一页。

要访问其余页面，请按照下一个链接查看Feed：< link rel =next

href =https://partner.homeaway.com/aggregator/homeaway/partners/search?partnerId=cj_all&format = cjAtom&affiliateID = 1&page = 2/>。最后一个

页面没有下一个链接。因此，代码可以在文档遍历时从文档中提取信息。

您应该每天处理一次Feed并缓存数据。在给定日期收到的数据应该替换前一天的任何数据。

例如，您可能在某一天列出1,2和3，在第二天，1,2 ，4。在这种情况下，您不应再存储或使用清单3.此外，

列表数据可能会随着所有者更新其列表而更改，因此应在您的系统中更新清单1和清单2。 br $>

Please someone help! I know I am overlooking something, but has anyone had any experience displaying an affiliate atom feed for homwaway in Razor using webmatrix or java. If I could only see an example I’m sure I could learn this, but I am having no luck at all finding one. Below is all the info they have on their website.

HomeAway Affiliate XML Feeds FAQ
Affiliate XML Data Feed FAQ
Getting started
The feeds that HomeAway are providing are XML atom feeds. XML (Extensible Markup Language) is a set of rules for encoding documents
electronically. It is common for XML to be used in interchanging data over the Internet. Therefore, in order to access the data you must parse the
feed.
Here are the basic steps for accessing and displaying xml feeds:
Step 1: Get the XML Feed
Step 2: Extract or Parse data from the feed
Step 3: Store data
Step 4: Display data
There are many different ways to extract or parse the data from the feed. A variety of APIs for accessing XML have been developed and used,
and some have been standardized.
Examples of pull parsers include StAX in the Java programming language, SimpleXML in PHP and System.Xml.XmlReader in the .NET
Framework. Other popular ones include the following:
FeedAPI - http://drupal.org/project/feedapi
SimplePie - http://simplepie.org/
PHP Universal Feed Parser -
http://www.ajaxray.com/blog/2008/05/02/php-universal-feed-parser-lightweight-php-class-for-parsing-rss-and-atom-feeds/
Accessing the data
The URL for accessing the Atom feed will be something like this:
https://partner.homeaway.com/aggregator/homeaway/partners/search?partnerId=cj_all&format=cjAtom&affiliateID=1. This will be the first page of
the feed.
To access the remaining pages, "walk" the feed by following the next links: <link rel="next"
href="https://partner.homeaway.com/aggregator/homeaway/partners/search?partnerId= cj_all&format=cjAtom&affiliateID=1&page=2"/>. The last
page will not have a next link. The code can thus extract information from the document as it traverses it.
You should walk the feed once a day and cache the data. The data received on a given day should replace any of the data from the day before.
For example, you may have listing 1, 2 and 3 one day, and on the next day, 1, 2, 4. In this case, you should no longer store or use listing 3. Also,
listing data may change as owners update their listings, so listings 1 and 2 should be updated in your system.
XML Feed Data
The data provided in the feeds includes the following:
Vacation Rental Name
Description of the Property
Property ID
URL of the listing at HomeAway.com
CJ Tracking URL
Image URL
Region (Country, State, Town, Zip)
Price
Currency
Period Type (Nightly – Weekly – Monthly)
Property Type (Condo, House, etc)
# of Bedrooms
# of People it Sleeps
# of Bathrooms
Hint – You can right click on the feed and ‘view source’ to see the data fields above!
