复制命名空间的所有元素，仅此而已 [英] Copy all elements of a namespace and nothing else
问题描述
我们有一堆文件是 html 页面，但其中包含额外的 xml 元素(都以我们的公司名称TLA"为前缀)来为我现在正在重写的旧程序提供数据和结构.
We have a bunch of files that are html pages but which contain additional xml elements (all prefixed with our company name 'TLA') to provide data and structure for an older program which I am now rewriting.
示例表单:
<html >
<head>
<title>Highly Simplified Example Form</title>
</head>
<body>
<TLA:document xmlns:TLA="http://www.tla.com">
<TLA:contexts>
<TLA:context id="id_1" value=""></TLA:context>
</TLA:contexts>
<TLA:page>
<TLA:question id="q_id_1">
<table>
<tr>
<td>
<input id="input_id_1" type="text" />
</td>
</tr>
</table>
</TLA:question>
</TLA:page>
<!-- Repeat many times -->
</TLA:document>
</body>
</html>
我的任务是编写一个预处理器来提取所有TLA"元素并忽略 html 元素
My task is to write a pre-processor that will extract all the 'TLA' elements and ignore the html elements
所需的 XML 输出:
Desired XML Output:
<?xml version="1.0" encoding="utf-8" ?>
<TLA:document xmlns:TLA="http://www.tla.com">
<TLA:contexts>
<TLA:context id="id_1" value=""></TLA:context>
</TLA:contexts>
<TLA:page>
<TLA:question id="q_id_1">
</TLA:question>
</TLA:page>
<!-- Repeat many times -->
</TLA:document>
这对于 XSLT 应该是可行的，但我无法制定正确的代码.这是我目前所拥有的:
This should be doable with XSLT but I'm unable to formulate the correct code. This is what I have so far:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
xmlns:tla="http://www.tla.com"
>
<xsl:output method="xml" indent="yes"/>
<xsl:template match="tla:*">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
这是提取我想要的元素(但不是它们的属性！)而且还提取了 html 元素的文本属性和内容.如何排除 html 元素及其内容?
Which is extracting the elements I want (but not their attributes!) but also extracts the text attributes and content of the html elements. How can I exclude the html elements and their content?
推荐答案
应该这样做:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:tla="http://www.tla.com">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
<xsl:strip-space elements="*" />
<xsl:template match="text()" />
<xsl:template match="tla:* | tla:*/@* | tla:*/text()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
在您的示例输入上运行时(一旦添加了缺少的命名空间声明)，结果是:
When run on your sample input (once the missing namespace declaration is added), the result is:
<TLA:document xmlns:TLA="http://www.tla.com">
<TLA:contexts>
<TLA:context id="id_1" value="" />
</TLA:contexts>
<TLA:page>
<TLA:question id="q_id_1" />
</TLA:page>
</TLA:document>
