xml - 尝试创建通用 XSL 以允许稍微不同的 XML 格式

Question

我是编写 XSL 转换的新手，我正在尝试创建一个涵盖特定 XML 格式的 XSL 我在这里有两个例子:

第二个在这里显示:

我正在尝试提取部分的总数，但想要一个对两者都适用的 XSL。我设法得到一个适用于下面显示的每个单独的，但似乎它们的 XPATH 对两者都不同，其中一个需要通过 XPATH 的前缀，而另一个不需要。显然另一个问题是他们的命名空间略有不同，有没有办法解决这个问题？

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="//edx:Programme" xmlns:edx="http://www.digitalproductionpartnership.co.uk/ns/as11/2012"><xsl:value-of select="/edx:Programme/Technical/Timecodes/TotalNumberOfParts" /></xsl:template>
</xsl:stylesheet>

第二个 XSL 在这里:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="//edx:Programme" xmlns:edx="http://www.digitalproductionpartnership.co.uk/ns/as11/2015"><xsl:value-of select="/edx:Programme/edx:Technical/edx:Timecodes/edx:TotalNumberOfParts" /></xsl:template>
</xsl:stylesheet>

所以，只是为了澄清一下，是否有一种方法可以编写单个 XSL 来从两个 XML 中提取部分数量，因此无论哪个 XML 是源，转换都适用于两者？

非常感激

Answer 1

如果将所写的两个模板(在 xsl:template 上带有本地 namespace 声明)放入单个样式表中，那么 XSLT 处理器将应用与输入格式匹配的模板。
