Groovy read values from xml

问题

I have a Sample Code where I'm trying to read data from an xml file and manipulating the values. This worked perfectly fine when I tried it on http://ideone.com

In my actual code I'm calling something like this

def xmlFile = "path/to/xmlfile.xml"
def tcproj = new XmlParser().parseText( getTemplate(xmlFile).toString() )

But when I use the same if condition specified in the Sample Code in my actual code, I get a completely different result.

On trying to debug I found that the result varied a lot. The result on my actual code with this when I tried to do

println records.supported_versions.version.any { println it; it.toString().matches( /$ver/ ) }

was this

version[attributes={}; value=[6.0.35.A]]
version[attributes={}; value=[7.0.25.B]]
false

When I do

println records.supported_versions.version.toString()

I get a result

[version[attributes={}; value=[6.0.35.A]], version[attributes={}; value=[7.0.25.B]]]

Can someone help me understand what's happening here and how to solve this?

You're using XmlParser instead of XmlSlurper as in that example...

To use XmlParser, you need to change the code to:

class xmlWorker {
  static def tcproj = '''<tcs>
                           <supported_versions>
                             <version>6.0.35.A</version>
                             <version>7.0.25.B</version>
                           </supported_versions>
                         </tcs>'''
}
def records = new XmlParser().parseText(xmlWorker.tcproj)

def ver = "6.0.35.A"

println "Version: " + ver

println records.supported_versions.version.any {
  println it.text()
  it.text().matches( /${ver}/ )
}

if( records.supported_versions.version.any { it.text().matches( /${ver}/ ) } ) {
  println "if"
} else {
  println "else"
}
