使用 XSLT 1.0/2.0 在元素上选择具有多个命名空间的元素

问题描述

我输入的 xml 包含具有多个命名空间的元素，我需要将此输入 xml 转换为另一种 xml 格式.但是我不确定如何在 xpath 中指定多个命名空间来选择具有两个命名空间a"和i"的元素 AVResult 的值

I have input xml which has elements with multiple namespaces,I need to transform this input xml into another xml format. However I am not sure how to specifiy multiple namespaces in xpath to select the value of the element AVResult which has two namespaces "a" and "i"

这里，如何包含两个命名空间来选择 AVResult ?

Here, How to include two namespace to select AVResult ?

推荐答案

AVResult 实际上有三个命名空间.它还采用其父节点 AVResponse (xmlns="http://info.com/Contracts") 的命名空间.但是，由于 AVResponse 的命名空间没有前缀，因此您必须在样式表标记中使用前缀创建对它的引用，您已经将其创建为 ns1.所以，任何时候你想引用 AVResponse 或者它的任何子节点或孙节点，你都必须使用 ns1 前缀.此外，您不能将 ns1 放在 exclude-result-prefixes 中并排除它.

AVResult actually has three namespaces. It also takes on the namespace for its parent node AVResponse (xmlns="http://info.com/Contracts"). But, since the namespace for AVResponse does not have a prefix, you have to create a reference to it with a prefix in your stylesheet tag, which you already created as ns1. So, any time you want to reference AVResponse or any of it's child or grandchild nodes you have to use the ns1 prefix. Also, you can't put ns1 in exclude-result-prefixes and exclude it.

xmlns:a="http://NamespaceOne.com"
xmlns:ns3="http://schemas.BaseMessages"
xmlns:i="http://NamespaceTwo.com"
exclude-result-prefixes="ns3 a i s b">


<xsl:template match="ns1:AVResult">
    do stuff
</xsl:template>
