檢索整個節點與的XmlSlurper

Question

字符串我想要檢索的<logs>元素爲String數組，我想以下幾點：

import groovy.util.XmlSlurper 

def payload = '''<logs> 
<log> 
    <text>LOG 1</text> 
    <timestamp>2017-05-18T16:20:00.000</timestamp> 
</log> 
<log> 
    <text>LOG 2</text> 
    <timestamp>2017-05-18T16:20:00.000</timestamp> 
</log> 
</logs>''' 

def logs = new XmlSlurper().parseText(payload) 
def result = [] 
logs.log.each{ 
    result.add(it) 
} 
result 

但是，我得到的數值，但我會想了解整個節點的文字，或多或少這樣的：

[<log> 
    <text>LOG 1</text> 
    <timestamp>2017-05-18T16:20:00.000</timestamp> 
</log>, 
<log> 
    <text>LOG 2</text> 
    <timestamp>2017-05-18T16:20:00.000</timestamp> 
</log>] 

這是與XmlSlurper在所有可能的或者我應該使用一些字符串操作？

Answer 1

您可以使用XmlUtil但必須刪除XML聲明：

import groovy.util.XmlSlurper 
import groovy.xml.XmlUtil 

def payload = '''<logs> 
<log> 
    <text>LOG 1</text> 
    <timestamp>2017-05-18T16:20:00.000</timestamp> 
</log> 
<log> 
    <text>LOG 2</text> 
    <timestamp>2017-05-18T16:20:00.000</timestamp> 
</log> 
</logs>''' 

def logs = new XmlSlurper().parseText(payload) 

def result = logs.log.collect { 
    XmlUtil.serialize(it).replaceAll(/<.xml.*?>/,"") 
} 

println result

試試這個：

def payload = '''<logs> 
<log> 
    <text>LOG 1</text> 
    <timestamp>2017-05-18T16:20:00.000</timestamp> 
</log> 
<log> 
    <text>LOG 2</text> 
    <timestamp>2017-05-18T16:20:00.000</timestamp> 
</log> 
</logs>''' 

def logs = new XmlSlurper().parseText(payload) 
def result = [] 
logs.log.each{ 
    result.add("<log> <text>" + it?.'text'.text() + "</text> <timestamp> " + it?.'timestamp'.text() + "</timestamp> </log>") 
} 
return result

你可以去：

def payload = '''<logs> 
<log> 
    <text>LOG 1</text> 
    <timestamp>2017-05-18T16:20:00.000</timestamp> 
</log> 
<log> 
    <text>LOG 2</text> 
    <timestamp>2017-05-18T16:20:00.000</timestamp> 
</log> 
</logs>''' 

def logs = new XmlParser().parseText(payload) 
def result = logs.log.collect { 
    def sw = new StringWriter() 
    def pw = new PrintWriter(sw) 
    new XmlNodePrinter(pw).print(it) 
    sw.toString().replaceAll('\\s', '') 
}
