通過在Groovy中通過XML Parser方法中的字符串傳遞標籤名來獲取標籤值

Question

如何通過傳遞標籤名稱而不使用硬編碼標籤名稱來獲取以下XML中的任何標籤（例如Quantity）的值 -

def temp1=""" 
<TradeRecord> 
    <TradeId>1000</TradeId> 
    <SecurityId>10382456</SecurityId> 
    <TradeType>SELLL</TradeType> 
    <TradeDate>2014-03-21</TradeDate> 
    <Broker>100</Broker> 
    <Exchange>1</Exchange> 
    <Status>INIT</Status> 
    <Quantity>125</Quantity> 
    <ApprovedBy /> 
</TradeRecord> 
""" 

def records = new XmlParser().parseText(temp1) 
//log.info records.Quantity[0].text()  By using this i am getting value but i want  'Quantity' to come from a string 
tag = 'Quantity' 
xy = records["Quantity"].value; 'This is not working 
log.info xy 

Answer 1

你應該能夠做到

records."$tag".text() 

Answer 2

你應該使用.text()方法

records[tag].text()
