Question

感谢您的光临并了解我是新手。所以对我来说似乎很容易对我来说很新鲜。

我做了一些关于如何使用javascript和/或php从.xml文件中提取数据的研究。我也可以使用html5 canvas（Construct 2）将这个.xml数据拉入移动应用程序

我的问题与节点本身无关，但后来又是。

如果节点有这样的文本就更容易了。

<item>Hi There</item>

而不是像我想要的那样的子节点。

<item game="powerball" nextjp="$67 Million" nextdd="Wednesday, August 10, 2016" winnum="20-33-36-47-52 PB12 X3" windd="Saturday, August 6, 2016" myflv="widget_pb.flv" winnumNM="20-33-36-47-52 PB12" name="POWERBALL">

我想分解节点，使其读取

Game
Next Jackpot
Next drawing
Winning Numbers
Game Played Date

如果我能找到一个已经拥有每个节点的xml而不是一个节点内的所有节点，那对我来说很容易。因此，我说我不需要完整的详细脚本演示，我只需要了解如何获取子节点数据。谢谢Jeremy C.

Answer 1

在这种情况下，我从字符串中加载了整个XML。在实际情况中，您可能需要使用ajax来拉它。

注意：您在评论中添加的URL，我从中获取此xml并不具有“允许*来源标题＆＃34;所以，那里的ajax会产生CORS错误。
