Parsing XML elements and store them in array
Hi Friends

Im so confused with using 'for' loop in ksh. I have a xml like the following:

Code:
<serviceProvider>	
			<serviceProviderID>1</serviceProviderID>
			<serviceProviderName>Balesh</serviceProviderName>
			<serviceFeeAmount>30.00</serviceFeeAmount>				
</serviceProvider>
<serviceProvider>	
			<serviceProviderID>1</serviceProviderID>
			<serviceProviderName>Balesh</serviceProviderName>
			<serviceFeeAmount>120.00</serviceFeeAmount>				
</serviceProvider>
<serviceProvider>	
			<serviceProviderID>1</serviceProviderID>
			<serviceProviderName>Balesh</serviceProviderName>
			<serviceFeeAmount>230.00</serviceFeeAmount>				
</serviceProvider>

I need to extract the value of <serviceFeeAmount> and store them in an array.

Please help me in how to use 'for' loop for this scenario, im confused...

Thanks in advance....

Parsing XML values can be complex specially if the tags and values are spread among multiple lines.

This code will extract the value, but it work only if both tags and value are in the same line:
Code:
sed '/serviceFeeAmount/!d;s/.*>\(.*\)<.*/\1/' Inp_File

Yes, but a preprocessing sed can pile lines into the buffer so as to ensure each <serviceProvider>...</serviceProvider> is now one line with no distracting whitespace ('\t' s/b real tab):
Code:
sed '
  s/[ \t]*\([<>]\)[ \t]*/\1/g
 ' | sed '
  /<serviceProvider>/{
    :loop
    /<\/serviceProvider>/s/[ \t]*\n[ \t]*//g
    t
    $b
    N
    b loop
   }
 '
