Extracting information from XML to excel
Hi,

I am trying to extract information from a XML file and write it to a excel sheet. I am not sure where to start from. Here is the content from my input XML file.

Code:
    <com.cloudbees.hudson.plugins.folder.properties.FolderProxyGroupContainer plugin="nectar-rbac@4.5">
      <groups>
        <nectar.plugins.rbac.groups.Group>
          <name>ATSCMViewer</name>
          <member>mmapp</member>
          <member>mmdep</member>
          <member>mmdev</member>
          <member>mmtest</member>
          <role>Viewer</role>
        </nectar.plugins.rbac.groups.Group>
        <nectar.plugins.rbac.groups.Group>
          <name>ATSCMIntegrator</name>
          <member>mmINT</member>
          <role>Integrator</role>
          <role>Viewer</role>
        </nectar.plugins.rbac.groups.Group>
      </groups>
      <roleFilters>
        <string>anonymous</string>
        <string>authenticated</string>
        <string>Developer</string>
      </roleFilters>
    </com.cloudbees.hudson.plugins.folder.properties.FolderProxyGroupContainer>

The Output in excel I am looking for is

Code:
column1           column2       column3
<name>              <role>       <member>
ATSCMViewer        Viewer         mmapp
                                  mmdep
                                  mmdev
                                  mmtest

ATSCMIntegrator    Integrator     mmINT
                    Viewer

Try this...
Code:
awk -F'>|<' '
  /<nectar.plugins.rbac.groups.Group>/{s=1}
  /<\/nectar.plugins.rbac.groups.Group>/{
    for(i=j+1;i<=m;i++) printf("%-30s%10s\n", "", mem[i])
    delete(mem)
    j=s=m=0
  }
  s && /name/{name=$3}
  s && /member/{mem[++m]=$3}
  s && /role/{
    if(++j==1) printf("\n%-20s%-10s%10s\n", name, $3, mem[1])
    else printf("%-20s%-10s%10s\n", "", $3, mem[j])
  }' infile

Please do show some effort!

Code:
$ cat file
    <com.cloudbees.hudson.plugins.folder.properties.FolderProxyGroupContainer plugin="nectar-rbac@4.5">
      <groups>
        <nectar.plugins.rbac.groups.Group>

          <member>mmtest</member>
          <role>Viewer</role>
        </nectar.plugins.rbac.groups.Group>
        <nectar.plugins.rbac.groups.Group>
          <name>ATSCMIntegrator</name>
          <member>mmINT</member>
          <role>Integrator</role>
          <role>Viewer</role>
        </nectar.plugins.rbac.groups.Group>
      </groups>
      <roleFilters>
        <string>anonymous</string>
        <string>authenticated</string>
        <string>Developer</string>
      </roleFilters>
    </com.cloudbees.hudson.plugins.folder.properties.FolderProxyGroupContainer>

Code:
$ cat tester.sh
awk  '
           function out(){
		           for(k=1;k<=MF;k++)
			   print ARR["N",k],ARR["R",k],ARR["M",k]
		           delete ARR
	                 }

                   NR==1 {
			   print "column1" OFS "column2" OFS "column3" RS  "<name>" OFS "<role>" OFS "<member>"
		         }

	         /<name>/{	 
	     		  if(flag==1){
					out()
					flag = n = m = r = 0
				     }	
	     		  ARR["N",++n] = $3
   			 }

	      /<member>/{
			  ++k
	     		  ARR["M",++m] = $3
	     		  MF = m
			}

		/<role>/{
             		  ARR["R",++r] = $3
	     		  flag=1
			  MF = MF > r ? MF : r
			}

	            END {
			  out()
			}
      ' OFS="\t" FS="[>|<]" file

Resulting
Code:
$ sh tester.sh
column1	column2	column3
<name>	<role>	<member>
ATSCMViewer	Viewer	mmapp
		mmdep
		mmdev
		mmtest
ATSCMIntegrator	Integrator	mmINT
	Viewer

if you need csv change OFS="\t" to OFS="," , that would result
Code:
$ sh tester.sh
column1,column2,column3
<name>,<role>,<member>
ATSCMViewer,Viewer,mmapp
,,mmdep
,,mmdev
,,mmtest
ATSCMIntegrator,Integrator,mmINT
,Viewer,

Function just prints array elements, once after loop array will be deleted
