那些遇到过的问题

将XML嵌入XML以便在Web浏览器中显示:我做错了什么？

ish*_*624 6 xml embed xslt

所以我试着去研究这个问题,而我几乎已经完成了我的智慧.我找到了一种在dpawson.co.uk上嵌入XML的方法,但我无法弄清楚我做错了什么.我在互联网上搜寻试图找到解决方案和解释,但没有人似乎有答案.

我正在尝试创建一个与服务器无关的文件,因此我可以将一个文件发送给我的同事,希望他们可以通过在Web浏览器中打开文件来查看该文件.

到目前为止,这是我的代码:

这是一个电影列表,其中包含我到目前为止看过多少电影,有多少我还没有看到,有多少我在制作列表之前看到的,我看电影的总时间,和每部电影的平均评分.

问题是所有变量都显示为零值,这会导致除以零,这也会在某些输出上产生NaN值.

任何人都可以提供的任何东西将不胜感激!

注1:该问题是导致通过嵌入XML元素嵌套层次的变化 <list> 的范围内 <doc> ,当你把XML和XSL到单个文件格式元素.解决方案/doc之前/list在所有XPath表达式中添加了解决方案,以便选择所需的元素,这些元素现在嵌套为更深层次的一个级别<doc> , <list>而不仅仅是后代<list>(就像两个文件分开时一样).

注2:xml-stylesheet类型也改为"text/xsl",作为与IE 8兼容的一步.对于"text/xml"类型,IE 8只显示文档树(包括XSL)作为XML,而与"text/xsl"它尝试 - 虽然相当不成功 - 应用转换.在IE 8中正确显示这个显示需要做更多的工作.请注意,任何类型的值在FireFox 7中都能正常工作.没有其他浏览器被测试过.

  • 快速更新:解决方案在Chrome 29和Firefox 23上运行正常.无法在IE10上运行(如果有人想知道的话) (2认同)
