本文介绍了如何为xml元素添加包含冒号(:)的属性,然后在groovy中对其进行序列化?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一些测试代码片段:
I have some test code snippet:
import groovy.xml.XmlUtil
class Greet {
Greet() { }
def salute() {
println "Hello !"
def input = """
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<application >
<activity android:name="me.aolphn.MainActivity">
</activity>
</application>
</manifest>
"""
// def root = new XmlParser(false, true).parseText(input)
def root = new XmlSlurper(false, true).parseText(input)
root.'application'.@'android:txt'='this is txt'
XmlUtil.serialize(root)
}
}
g = new Greet() // create object
g.salute()
我在此处在线运行,上面的代码会引起一些异常,错误消息如下所示
And I run it online in here,above code will encouter some exception,error message as follow showing
groovy.lang.GroovyRuntimeException: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 24; Element type "application" must be followed by either attribute specifications, ">" or "/>".
at Greet.salute(Script1.groovy:24)
at Greet$salute.call(Unknown Source)
at Script1.run(Script1.groovy:29)

问:我需要什么?
- A:我想添加一个包含xml元素名称空间的属性.例如,我想要一个元素'application'的属性'android:xxx',XmlUtil.serialize()添加后会遇到错误.帮我.任何责任将不胜感激.
- Q:What I'm need?
- A:I want add an attribute which contains namespace for xml element.As my example ,I want and an attribute 'android:xxx' for element 'application',XmlUtil.serialize() will encounter error after adding that.Please help me. Any responsibility will be appreciated.
推荐答案
最后,我通过XmlParser
而不是'XmlSlurper'解决了此问题.以下是正确的方法.
Finally I address this issue by XmlParser
instead of 'XmlSlurper'.The following is right way.
import groovy.xml.XmlUtil
import groovy.xml.StreamingMarkupBuilder
class Greet {
def name
Greet(who) { name = who[0].toUpperCase() +
who[1..-1] }
def salute() {
println "Hello !"
def input = """
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<application xmlns:android="http://schemas.android.com/apk/res/android"
android:txt="this is origin">
<activity android:name="com.cloud.chsocialtest.MainActivity">
</activity>
</application>
</manifest>
"""
def root = new XmlParser(false, true).parseText(input)
//def root = new XmlSlurper(false, true).parseText(input).declareNamespace(android:"http://schemas.android.com/apk/res/android")
//def writer = new StringWriter()
//root.'application'.attributes().put('@android:txt1','t1')
root.'application'[0].attributes()['android:new']='txt aa'
println("========:\n"+
XmlUtil.serialize(root))
//print writer.toString()
}
}
g = new Greet('world') // create object
g.salute()
