Thanks for the reply.but not the issue in my case timer and thread already included in my topic. my problem is .. for eg i call one of the rest endpoint and it gives xml responses like this

If yes, it should be easy enough, you don't need all that response.getOutputStream() and other code. Take a look at StringWriter class available in Java.

inside token the methodname and url calling is there XmlRpcSerialzer pre-defined class they use XmlRpcSerializer.serialize(Object value,Writer writer) return method as XmlRpcSerializer.serialize( token, writer );

sorry i cannot able to attach java file,error like "Files with the extension .java are not allowed as attachment in the message."
so i post my java file here but it is not runnable condition beacuse url and apikey is sensitive i cant able to hardcode it,please try to understand my code

what i want the output is i mentioned before

Java and all other programming languages care a lot about "grammar" - if you can't manage to keep your spelling and capitalization straight in your code perhaps you should consider a career in another field.

Programming is - above all - about clarity of expression. If you can't express your problem clearly, you can't solve it.


as a student i understood what you said,i follow your words from my next post, dont insert smilies while giving worthable advice

First you have to decide what you want to do. Do you want to concatenate (what you called "concat") the two documents in some way? Or do you want to merge them in some way? The two words mean very different things. And your examples of possible inputs have no obvious relationship, so it's impossible to tell what your desired output is. It certainly doesn't help that you didn't tell us what your desired output is from those inputs.

Sorry paul,for my grammatical mistakes i want desired output like

please help me am helpless

Is it that hard to pay that little respect to one's own work or is it that somebody, myself for instance, is accused of not being nice ? I think before one asks question, one starts with acquiring the skill of reading and comprehension otherwise I don't see the end of the loop of eternal return.

really i feel depressed please provide answer if you understand means,rather than seeing grammatical some other mistakes

Paul Clapham wrote:Well yes, in fact we DO expect examples which are not misleading. Have a look at our FAQ entry PostRealCode to find out why.

Hai Paul, My xml is dynamic which it is come from some third party server so i want to mash or merge that two files,

so clean example


so here is two files 1st xml file have 10 nodelist and 2nd xml file have 20 nodelist

by using this code

i try my level best to understand my probelm

please help me to get rid of this problem can i able to concat 2 xml file nodelist length? or any other alternate solution to merge xml files with presence of all nodelist>

g tsuji wrote:Do you understand xml is case-sensitive to begin with ? And then you said your output is <root/> : it seems to be a miracle as well. (What is the complete code to arrive to that result ?) And then if your for loop has index i applied to "Root" (or "root"), it should not be an index apt for element d, e, f. There is only one root in a well-formed document in any way. And then if you start with getElementsByTagName() for "subroot", your code may be closer to what you need but the code is still incredibly confusing. How about you make a more reasonable effort to clean up the logic and the code on your side before posting ? Every single line seems to be dubious at present making help to be a pain rather than a joy. That is my impression with no disguise.

am just mention xml eg here for better understand,are you expect code logic and case senesitive issue in example?
