将 XML API 数据解析到 Rails 应用程序

Question

我一直在尝试在 Google 上找到一些有关如何执行此操作的指南或提示，但无济于事。我什至不知道标题是否正确。我不知道它是元编程，还是只是将 XML 数据解析到 Rails。

假设我有一个同意提供 XML API 来向我的网站提供数据的第三方。我想接收数据并将其存储在我的模型中。我通过 SO 进行了检查，发现这个链接部分回答了我的问题：Parse then Store XML Data from API in Ruby on Rails，但我想知道应用于我的第三方方法的确切方法。

我的模型列中有PropertyNumber。如何编写以使用结构化 URL 解析信息并将其存储到我的模型？

其实，有什么链接可以让我了解所有这些吗？

非常感谢！
