问题描述
我有一个XML模式，我需要从中提取值，但是运气不太好.
I have an XML schema that I need to extract values from but I am not having much luck.
来源模式为:
<Reading>
<State>
<StateValues>
<Name>
<Value>
</StateValues>
</State>
<Reading>
XML的示例为:
<Reading>
<State>
<StateValues>
<Name>Reading1</Name>
<Value>1234</Value>
</StateValues>
<StateValues>
<Name>Reading2</Name>
<Value>2345</Value>
</StateValues>
</State>
<State>
<StateValues>
<Name>Reading3</Name>
<Value>4321</Value>
</StateValues>
</State>
<Reading>
我需要的结果是:
<Readings>
<Reading1>1234</Reading1>
<Reading2>2345</Reading2>
<Reading3>4321</Reading3>
</Readings>
我无法控制架构.
我一直在尝试使用xsl:foreach和xsl:if来检查名称，但是我只是将第一个值重复3次.有小费吗?我已经尝试了2天，但我不是XSLT专家...
I have been trying to use a xsl:foreach with an xsl:if that checks the name but I just get the first value repeated 3 times. Any tips? I've been trying to figure this out for 2 days and I am not an XSLT expert...
谢谢. 对不起，您没有发布我的XSLT.我尝试了多个版本，但认为它没有用.在这里:
Thanks. EDIT : Sorry for not posting my XSLT. I had tried several versions and didn't think it would be useful. Here it is:

推荐答案
foreach和if在XSLT中通常是错误的方法.将模板应用于模式要有效得多.在这种情况下，您可以使用两种方法:第一种设置根元素并匹配您要使用的元素:
foreach and if are usually the wrong approach in XSLT. It is far more effective to apply templates to patterns. In this case you can use two: the first sets up the root element and matches the elements you want to work with:
<xsl:template match='/'>
<Readings>
<xsl:apply-templates select='Reading/State/StateValues'/>
</Readings>
</xsl:template>
，当找到匹配项并完成核心工作时，上述触发的秒数.这里的复杂性是动态创建一个元素，这意味着使用{XPath}语法从输入文档中获取名称:
and a second that the above triggers when a match is found that will do the core work. The complexity here is creating an element dynamically which means using the {XPath} syntax to get the name from the input document:
<xsl:template match='StateValues'>
<xsl:element name='{Name}'>
<xsl:value-of select='Value' />
</xsl:element>
</xsl:template>
