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="www.tla"> <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="www.tla"> <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="www.w3/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" xmlns:tla="www.tla" > <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="www.w3/1999/XSL/Transform" xmlns:tla="www.tla"> <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="www.tla"> <TLA:contexts> <TLA:context id="id_1" value="" /> </TLA:contexts> <TLA:page> <TLA:question id="q_id_1" /> </TLA:page> </TLA:document>更多推荐
复制命名空间的所有元素,仅此而已
