how to read the variable from tags based on appropriate tag
Hi,

I've got a situation where I need to read the values from XML tags in a file. Please find the sample xml code below:

Code:
<entity>
  <name>Testing</name>
  <number>11</number>
  <template>testing.testing</template>
</entity>
<entity>
  <name>Development</name>
  <number>13</number>
</entity>
<entity>
  <name>Support</name>
  <number>18</number>
  <location>US</location>
  <template>analyze.analyze</template>
</entity>

Now, i want to retrieve the <name> tag field and <template> tag value using single command. But, the <template> tag doesnot exists for some fields.

output should be:
Code:
NAME - TEMPLATE
Testing - testing
Development - 
Support - analyze

In the output, TEMPLATE column should have only first string before . (period) sign.

Please help me out!!!

Thanks in advance

This works on your sample data:
Code:
awk -F'[<>.]' '/<entity>/,/<\/entity>/{
if(/<name>/) n=$3
if(/<template>/) t=$3
if(/<\/entity>/) {print n,t;n=t=""}}' OFS=' - ' file

Code:
awk -F "[<>.]" 'NR==1{print "Name Template"}
/<name>/{if(s){print s"-";s=$3}else{s=$3}}
/<template>/{s=s"-"$3;print s;s=""}' file

Hi Thanks for the update.

A small update that if I don't want to read the values of <name> of <entity> in which <template> doesn't present. Could you help??

You could have mentioned that in the original post itself. Your output in that post did not require this constraint. In future, mention your requirements clearly and fully.
Code:
awk -F'[<>.]' '/<entity>/,/<\/entity>/{
if(/<name>/) n=$3
if(/<template>/) t=$3
if(/<\/entity>/) {if(t) print n,t;n=t=""}}' OFS=' - ' file

Hi

It works fine. Thank you. Apologize to bother you again.

I've got an another scenario to read values. Please find the below sample xml code:

Code:
<entity>
 <name>Testing</name>
 <number>13</number>
 <template>analyze.analyze</template>
 <requirement>
    <prerequire>
       <prerequireId>12</prerequireId>
       <prerequire>439</prerequire>
   </prerequire>
  </requirement>
</entity>
<entity>
 <name>Support</name>
 <number>19</number>
 <template>testing.testing</template>
 <requirement>
    <prerequire>
       <prerequireId>10</prerequireId>
       <prerequire>9382</prerequire>
   </prerequire>
    <prerequire>
       <prerequireId>10</prerequireId>
       <prerequire>9382</prerequire>
   </prerequire>
  </requirement>
</entity>
<entity>
 <name>Development</name>
 <number>14</number>
 <template>testing.testing</template>
 <requirement>
    <prerequire>
       <prerequireId>11</prerequireId>
       <prerequire>1928</prerequire>
   </prerequire>
    <prerequire>
       <prerequireId>12</prerequireId>
       <prerequire>1458</prerequire>
   </prerequire>
    <prerequire>
       <prerequireId>9</prerequireId>
       <prerequire>9894</prerequire>
   </prerequire>
  </requirement>
</entity>

The output should display as below:
Quote:
Name Template Prequire1 Prequire2 Prequire3
Testing analyze 439
Support testing 9382 9382
Development testing 1928 1458 9894
In the above sample xml code, the number of <prequire> tag may vary or may not exists.
Please help!!!!
