XmlSlurper.appendNode 不改变大小
我使用 XmlSlurper 处理 XML。在我更新之前它工作得很好。 appendNode 不反映大小。
结构更新后如何使用 XmlSlurper?
XML 定义:
def CAR_RECORDS = '''
<records>
<car name='HSV Maloo' make='Holden' year='2006'>
<country>Australia</country>
<record type='speed'>Production Pickup Truck with speed of 271kph</record>
</car>
<car name='P50' make='Peel' year='1962'>
<country>Isle of Man</country>
<record type='size'>Smallest Street-Legal Car at 99cm wide and 59 kg in weight</record>
</car>
<car name='Royale' make='Bugatti' year='1931'>
<country>France</country>
<record type='price'>Most Valuable Car at $15 million</record>
</car>
</records>
'''
代码女巫失败:
def records = new XmlSlurper().parseText(CAR_RECORDS)
records.appendNode( { car(make:'BMW') } )
assert 4 == records.car.size() //fails!!! size == 3
打印出包含 BMW 汽车的 XML
def xmlOut = new groovy.xml.StreamingMarkupBuilder()
def temp = xmlOut.bind{
mkp.yield records
}
println temp
I work with XML using XmlSlurper. It works fine until I update it. The appendNode doesn't reflect the size.
How to worked with XmlSlurper after structure update?
XML definition:

'''
Code witch fails:
def records = new XmlSlurper().parseText(CAR_RECORDS)
records.appendNode( { car(make:'BMW') } )
assert 4 == records.car.size() //fails!!! size == 3
Print out XML including BMW car
def xmlOut = new groovy.xml.StreamingMarkupBuilder()
def temp = xmlOut.bind{
mkp.yield records
}
println temp

您可以使用 XmlSlurper 再次读取新创建的结构。
You can read the newly created structure again using the XmlSlurper.
尝试此
更新:实际上此代码无法编译(请参阅注释),因此我稍后会发布我自己的解决方法结果。
在某些项目中,我使用了模板字符串,例如:
您可以像这样附加节点(lang Groovy):
Try this
update: actually this code doesn't compile(see comments) so i'll post my own workaround results later.
In some project i used template string like:
You can append node like that(lang Groovy):
