使用位置来计算节点 - 有时枚举从 0 而不是 1 开始
嘿伙计们， 我有一段相当笨拙的 xslt，我用它来将 SOAPUI 测试用例转换为更易读的格式。目前，它使用以下
我的问题 枚举测试用例有时，测试用例枚举会开始从 0 开始，有时从 1 开始。我不明白为什么会发生这种情况？这与位置选择器的实现方式有关吗？有没有更简洁的方法来计算节点的实例数？
非常感谢，
Richard
这是完整的代码 - 无样式。

Hey folks,
I've got this rather clumbsy piece of xslt which I use to transform SOAPUI test cases into a more readable format. Currently it enumerates the test cases using the following
<xsl:value-of select="position()-3"/>
My question Sometimes the test case enumeration starts at 0 and sometimes it starts at 1. I don't understand why this is happening? Is it something to do with how the position selector is implemented? Is there a neater way to count instances of a node?
Many thanks,
Richard

我建议您使用
count()：这将返回节点相对于其所有兄弟元素（从 1 开始）的当前位置。
根据上下文，
position()可能不是正确的方法。I suggest you to use
count():This returns the current position of the node respect to all its sibling elements (1-based).
position()might be not the proper way depending on the context.以下是使用
count()更有效：就是这么简单！默认情况下，
Here is how you would use
<xsl:number>, which is more efficient than usingcount():It's that simple! By default,
<xsl:number>counts the nodes of the same node kind (in this case, elements) and the same element name as the context node... which is what you want here, I believe. So it will count<con:testCase>elements.position()的问题是它可以（并且经常）包含您不期望的节点，例如文本甚至空白节点，如果读取的 XML 保留了它的话。根据您的具体要求，您可以计算前面同级的数量（如 @empo 所描述），或者可能值得研究
The problem with
position()is it can (and frequently does) include nodes you don't expect, such as text or even whitespace nodes, if whatever read the XML preserved it.Depending on your precise requirements, you can count the number of preceding siblings (as @empo described), or it might be worth looking into the
<xsl:number>instruction.
