有人知道一个好的scala库可以从XML中删除/压缩空格吗?
<foo> <bar>hello world</bar> <baz> xxx </baz> </foo>
为:
<foo><bar>hello world</bar><baz>xxx</baz></foo>

scala.xml.Utility.trim()应该做你想做的事:
scala> val x = <foo>
| <bar>hello world</bar>
| <baz> xxx </baz>
| </foo>
x: scala.xml.Elem =
<foo>
<bar>hello world</bar>
<baz> xxx </baz>
</foo>
scala> scala.xml.Utility.trim(x)
res0: scala.xml.Node = <foo><bar>hello world</bar><baz>xxx</baz></foo>

无论它值多少,这就是我现在在“自己动手”策略中所做的事情:
def compactXml(xml: Node): Node = { (xml map { case Elem(prefix, label, attributes, scope, children @ _*) => { Elem(prefix, label, attributes, scope, children.map(compactXml(_)) :_*) } case Text(data) => Text(data.trim) case x => x }).first }
