XML 操作 [英] XML Manipulation

问题描述

我创建了一个 XML 文件并成功地使用 xsd 模式对其进行了验证，然后创建了一个 xslt 文件以将 xml 文件上的数据转换为表格但是每次尝试在浏览器中打开它时，数据都显示在同一行而不是表格中，我很确定我的代码是正确的，但我不知道为什么它不起作用，这里是3个文件:https://www.dropbox.com/sh/gggkh4wg94simrl/2GbiHAGkVF

i created an XML files and succeeded validating it with an xsd schema , then a created an xslt file to turn the data on the xml file into a table but every time time a tried to open it into a browser , data are displayed in the same line not on a table , i'm pretty sure that my code is correct and i don't know why it doesn't work , here is the 3 files : https://www.dropbox.com/sh/gggkh4wg94simrl/2GbiHAGkVF

推荐答案

也许这是您问题中的一个错字，但原文如此"表明不是，因此问题可能出在这一行

Maybe this is a typo in your question, but the "sic" suggests not, therefore the issue could be with this line

<xsl:template match="Opertaion"> <!-- [sic] -->

源 XML 中没有Operation"元素，只有Operation"元素.如果您更改模板以匹配操作"而不是操作"，它应该会按预期工作.

There is no "Opertaion" element in the source XML, only an "Operation" element. If you change template to match "Operation" and not "Opertaion" it should work as expected.

唯一的混淆是您说数据显示在同一行而不是表格中".通常这是有道理的，因为 XSLT 具有内置模板的概念，在它无法找到 XSLT 文档中指定的节点的匹配项时使用该概念.内置模板将为找到它们的文本节点输出文本，但对于其他节点，只需继续处理其子节点.这将解释为什么你得到一行纯文本.

The only confusion is where you say "data are displayed in the same line not on a table". Normally this would make sense, because XSLT has the concept of built-in templates, which are used where it can't find a match for a node specified in the XSLT document. The built-in templates will output text for text nodes where it find them, but for other nodes just continue processing its children. This would explain why you got a line of just text.

但是，您的 XSLT 中确实有这一行

However, you do have this line in your XSLT

<xsl:template match="node()|@*"/>

在这种情况下，这将匹配操作"，因此此时停止处理，这意味着您实际上不应获得任何文本输出.当然，一旦您将模板匹配从操作"更正为操作"，这将不是问题.

This would match "Operation" in this case, and so stop processing at this point, meaning you should not actually get any text output. Of course, as soon as you correct the template match from "Opertaion" to "Operation", this won't be an issue.
