Question
I have this xml, i took it in xml a GPathResult object
how can I get Microsoft(R) Windows(R) Server 2003 Enterprise x64 Edition
based on checking with the field
value as OS Name
using groovy xml slurping
<client productname="abp">
<machine>
<env>
<variable name='ALLUSERSPROFILE' value='C:\Documents and Settings\All Users' />
<variable name='APPDATA' value='C:\Documents and Settings\Administrator\Application Data' />
<variable name='OS' value='Windows_NT' />
<variable name='COMPUTERNAME' value='AbhishekPC' />
</env>
<osinfo>
<osinfo field='OS Name' information='Microsoft(R) Windows(R) Server 2003 Enterprise x64 Edition' />
<osinfo field='OS Version' information='5.2.3790 Service Pack 2 Build 3790' />
<osinfo field='OS Manufacturer' information='Microsoft Corporation' />
<osinfo field='OS Configuration' information='Standalone Server' />
<osinfo field='OS Build Type' information='Multiprocessor Free' />
</osinfo>
</machine>
</client>
Here is the parsing code
def file = new File(filepath)
def gpathResult = new XmlSlurper().parse(file)
summary.productname=gpathResult.@product.text()
log.info gpathResult.system.osinfo.osinfo.@field.text()
System.out.println("HI 1"+gpathResult.machine.environment.variable.@name.text());
System.out.println("HI 2"+gpathResult.machine.osinfo.osinfo.@field.text());
if(gpathResult.machine.environment.variable.@name.text().equals("OS"))
{
summary.osname=gpathResult.machine.environment.variable.@value.text()
}
if(gpathResult.machine.environment.variable.@name.text().equals("COMPUTERNAME"))
{
summary.hostname=gpathResult.machine.environment.variable.@value.text()
}
Here HI 1
prints all the environments name attribut values but HI 2
only prints HI 2
here is the snapshot
here is what solved after i traversed
def vals1=gpathResult.machine.env.variable.findAll{it.@name=='COMPUTERNAME'}.@value.text()
println vals1
csmSummary.hostname=vals1
def vals2=gpathResult.machine.env.variable.findAll{it.@name=='OS'}.@value.text()
println vals2
csmSummary.osname=vals2
Solution
Strange... if I do this (with Groovy 1.8)
def gpathResult = new XmlSlurper().parseText( $/<client productname="abp">
<machine>
<env>
<variable name='ALLUSERSPROFILE' value='C:\Documents and Settings\All Users' />
<variable name='APPDATA' value='C:\Documents and Settings\Administrator\Application Data' />
<variable name='OS' value='Windows_NT' />
<variable name='COMPUTERNAME' value='AbhishekPC' />
</env>
<osinfo>
<osinfo field='OS Name' information='Microsoft(R) Windows(R) Server 2003 Enterprise x64 Edition' />
<osinfo field='OS Version' information='5.2.3790 Service Pack 2 Build 3790' />
<osinfo field='OS Manufacturer' information='Microsoft Corporation' />
<osinfo field='OS Configuration' information='Standalone Server' />
<osinfo field='OS Build Type' information='Multiprocessor Free' />
</osinfo>
</machine>
</client>/$ )
println "HI 1 ${gpathResult.machine.env.variable.@name*.text()}"
println "HI 2 ${gpathResult.machine.osinfo.osinfo.@field*.text()}"
it prints out:
HI 1 [ALLUSERSPROFILE, APPDATA, OS, COMPUTERNAME]
HI 2 [OS Name, OS Version, OS Manufacturer, OS Configuration, OS Build Type]
Can you try that code (assuming you are using 1.8, the latest version of Groovy -- if not, you will need to use """
instead of $/
for the string delimiters, and escape the \
chars)
[edit] It's probably just because you are using gpathResult.machine.environment.variable
instead of gpathResult.machine.env.variable
to traverse the env nodes, you'd do something like:
gpathResult.machine.env.variable.each { node ->
println "${node.@name.text()} contains ${node.@value.text()}"
}
