在groovy XMLslurper中过滤特定标记

XmlSlurper 您访问 element 标记为 NodeChildren 哪个实现了 Iterable 接口。这就是为什么可以应用以下操作:

1. Iterable.first() ) :

   element.description.first()?.text()
   

2. 获取类型为的第一个描述标记 DETAILED ( Collection.find(Closure cl) ):

   element.description.find { it.@type == 'DETAILED' }?.text()
   

3. Iterable.join(String separator) ):

   element.description.join(' ')
   

完整示例:

def xml = '''
<element name="ABC">
    <description>lorem ipsum</description>
    <description>foo</description>
    <description type="DETAILED">some text</description>
</element>
'''

def element = new XmlSlurper().parseText(xml)

println element.description.first()?.text()
println element.description.find { it.@type == 'DETAILED' }?.text()
println element.description.join(' ')

lorem ipsum
some text
lorem ipsum foo some text
