Extract string from XML using Groovy

Question

我有一个XML节点，我想检查特定的字符串，例如<name.firstname>john</name.firstname>因此我想遍历整个xml文件并查找所有名字，然后获取值为john的值。谁能帮我这个

Answer 1

Suppose the XML was formatted like this:

<results>
 <person>
  <name.firstname>john</name.firstname>
 </person>
 <person>
  <name.firstname>mary</name.firstname>
 </person>
</results>

With Groovy and XmlSlurper you can parse out the first name element with following code:

def results = new XmlSlurper().parseText(text) 
def people = results.person // list of person elements of type NodeChildren
people.each{ person ->
 String name = person."name.firstname".text()
 println name
}

You need to quote the "name.firstname" element since the "." would be confused with the XPath notation.
