从一个节点提取xml值 [英] extract xml value from one node

问题描述

 <  预订 >  
 <   booking_parts  >  
 
 <   quote  >  
 
 <   quote_entry     cet_id   =     amoount   =  20    /  >  
 <   quote_entry     cet_id   =  B    amoount   =  40    /  >  
 
 <  < span class =code-leadattribute> / quote  >  
 
 < ;   / booking_parts  >  
 
 <   / booking  >  

我想从这个xml获得20金额，任何想法？

解决方案

好吧我再见 已成功检索到所需的XmlNode。剩下的就是从该节点检索所需的属性。

所以这样的事情：

  Dim  bookAmoount = Book.Attributes（  amoount）。 

如果您感兴趣，可以使用以下内容简化代码：

 < span class =code-keyword> Dim  bookAmoount = doc.SelectSingleNode（  // quote / quote_entry [@ cet_id ='A']）。属性（  amoount）。值

<booking>
<booking_parts>

<quote>

 <quote_entry cet_id="A" amoount="20" /> 
<quote_entry cet_id="B" amoount="40" /> 

</quote>

</booking_parts>

</booking>

I want to get amount 20 from this xml, any idea?

解决方案

Hi, well I see you have successfully retrieved the desired XmlNode. All that is left for you is to retrieve the required attribute from that node.
So something like this:

Dim bookAmoount = Book.Attributes("amoount").Value

Also just in case you're interested you can simplify your code with something like this:

Dim bookAmoount = doc.SelectSingleNode("//quote/quote_entry[@cet_id='A']").Attributes("amoount").Value
