Merging multiple xmls into a single xml using bash?

[skove22]

i'm fairly new to xml so my apology if my question is stupid.is there a way to merge multiple xmls in to one? maybe using bash? how? example: ${checkout.response} cd ${checkout.root} ${checkout.response} rm -rf ${checkout.applianceDir} ${checkout.response} mkdir ${checkout.applianceDir} ${checkout.response} rm -rf ${return.root}/${checkout.applianceDir}/${branch.tag} ${checkout.response} mkdir ${return.root}/${checkout.applianceDir}/${branch.tag} ${checkout.response} chmod 777 ${return.root}/${checkout.applianceDir}/${branch.tag} ${checkout.response} mkdir ${return.root}/${checkout.applianceDir}/${branch.tag}/ma ${checkout.response} chmod 777 ${return.root}/${checkout.applianceDir}/${branch.tag}/ma ${checkout.response} mkdir ${return.root}/${checkout.applianceDir}/${branch.tag}/xl ${checkout.response} chmod 777 ${return.root}/${checkout.applianceDir}/${branch.tag}/xl ${checkout.response} mkdir ${return.root}/${checkout.applianceDir}/${branch.tag}/med ${checkout.response} chmod 777 ${return.root}/${checkout.applianceDir}/${branch.tag}/med ${checkout.response} mkdir ${return.root}/${checkout.applianceDir}/${branch.tag}/private ${checkout.response} chmod 777 ${return.root}/${checkout.applianceDir}/${branch.tag}/private ${checkout.response} svn --username ${svn.username} --password ${svn.password} list ${svn.server}/${svn.module}/${branch.tag}/${checkout.applianceDir} ${checkout.response} svn --username ${svn.username} --password ${svn.password} checkout ${svn.server}/${svn.module}/${branch.tag}/${checkout.applianceDir} ${checkout.applianceDir} ${checkout.response} can i make it shorter rather than all these read and write?
