计算xml文件中元素的数量 [英] Counting number of element in xml file

问题描述

首先，我引用了该帖子如何获取XML或XElement变量中的特定元素计数，并且无法解决我所面临的问题，所以我正在写这篇文章. xml的部分如下所示，我想计算元素的数量，即在modelvariables节点中发生次数标量的数量，如下所示

First of all I referred this post How to get specific element Count in XML or XElement variable and could not solve the problem which i was facing so i am writing this. The part of the xml is given as below I want to count the number of element that is number of occurance scalarvariable in modelvariables node as shown below

<ModelVariables>
 <ScalarVariable name="x" valueReference="0" description="the only state"causality="local" variability="continuous" initial="exact">
    <Real start="1"/>
 </ScalarVariable>
 <ScalarVariable name="der(x)" valueReference="1" causality="local" variability="continuous"        initial="calculated">
    <Real derivative="1"/>
 </ScalarVariable>
 <ScalarVariable name="k" valueReference="2" causality="parameter" variability="fixed" initial="exact">
    <Real start="1"/>
 </ScalarVariable>
</ModelVariables>

我定义为

XmlDocument doc =新的XmlDocument(); doc.Load(@"W:\ Prajwal \ FMU_EXTRACT \ modelDescription.xml");

XmlDocument doc = new XmlDocument(); doc.Load(@"W:\Prajwal\FMU_EXTRACT\modelDescription.xml");

我已经将节点列表创建为

and i have created nodelist as

XmlNodeList nodeList = (XmlNodeList)doc.DocumentElement.SelectNodes("//ModelVariables/ScalarVariable");

XmlNodeList nodeList = (XmlNodeList)doc.DocumentElement.SelectNodes("//ModelVariables/ScalarVariable");

我需要获取标量变量
