Groovy- searching and excretion xml code from log file

I have so many texts in log file but sometimes i got responses as a xml code and I have to cut this xml code and move to other files. For example:

sThread1....dsadasdsadsadasdasdasdas.......dasdasdasdadasdasdasdadadsada
important xml code to cut and move to other file: <response><important> 1 </import...></response>
important xml code to other file: <response><important> 2 </important...></response>
sThread2....dsadasdsadsadasdasdasdas.......dasdasdasdadasdasdasdadadsada

Hindrance: xml code starting from difference numbers of sign (not always start in the same number of sign)

Please help me with finding method how to find xml code in text Right now i tested substring() method but xml code not always start from this same sign :(

EDIT: I found what I wanted, function which I searched was indexOf(). I needed a number of letter where String "Response is : " ending: so I used:

int positionOfXmlInLine = lineTxt.indexOf("<response")

And after this I can cut string to the end of the line : 

def cuttedText = lineTxt.substring(positionOfXmlInLine);

So I have right now only a XML text/code from log file. Next is a parsing XML value like BDKosher wrote under it. Hoply that will help someone You guys

You might be able to leverage XmlSlurper for this, assuming your XML is valid enough. The code below will take each line of the log, wrap it in a root element, and parse it. Once parsed, it extracts and prints out the value of the <important> element's value attribute, but instead you could do whatever you need to do with the data:

def input = '''
sThread1..sdadassda..sdadasdsada....sdadasdas...
important code to cut and move to other file: **<response><important value="1"></important></response>**
important code to other file: ****<response><important value="3"></important></response>****
sThread2..dsadasd.s.da.das.d.as.das.d.as.da.sd.a.
'''

def parser = new XmlSlurper()
input.eachLine { line, lineNo ->
    def output = parser.parseText("<wrapper>$line</wrapper>")
    if (!output.response.isEmpty()) {
        println "Line $lineNo is of importance ${[email protected]()}"
    }
}

This prints out:

Line 2 is of importance 1
Line 3 is of importance 3
