You could read the file using XML::LibXML and store the contents in a CSV file (comma delimited)

http://search.cpan.org/dist/XML-LibXML/ explains the packages in XML::LibXML (pay attention to the Documentation links for Document and Element)

GO through and read the nodes in your XML file, and construct a CSV file. You can then read (import) the file in excel

You might be able to use the XML::Simple module.  This makes it very easy to read the XML file, but you don't get quite as much control over how it is read.  Whether it works will depend on your specific requirements.

Writing to a csv file would be easiest, and excel will be able to read it.  If you need more control over the output, you can use Spreadsheet::WriteExcel.

Hi Adam,

could you give a smple script for reading an xml file into an csv file or an excel sheet.

say the sml file is as below.

<architectures>
      <architecture>
      <name>Pace5</name>
      <testcases>
<testcase>tc_arm_icache<testcase>
<cache>
      <icache_size>32K</icache_size>      
      <dcache_size>4K</dcache_size>
</cache>
<testcase>tc_arm_idcache<testcase>
<cache>
      <icache_size>32K</icache_size>      
      <dcache_size>32K</dcache_size>
</cache>
<testcase>tc_arm_idcache<testcase>
<cache>
      <icache_size>32K</icache_size>      
      <dcache_size>4K</dcache_size>
</cache>
            </testcases>            
      </architecture>
<architecture>
      <name>Faraday</name>
      <testcases>
<testcase>tc_arm_dcache<testcase>
<cache>
      <icache_size>16K</icache_size>      
      <dcache_size>4K</dcache_size>
</cache>
<testcase>tc_arm_icache<testcase>
<cache>
      <icache_size>4K</icache_size>      
      <dcache_size>16K</dcache_size>
</cache>

How do you want that to become a CSV file.  Post an example of the desired output.

hi adam,

the output should be as below.Along with the above xml file we have to read data from another xml file:
File2.xml
<testcase>
<number>tc_arm_icache</number>
      <use>Yes</use>
</testcase>
<testcase>
<number>tc_arm_dcache</number>
      <use>Yes</use>
</testcase>
<testcase>
<number>tc_arm_idcache</number>
      <use>Yes</use>
</testcase>
<testcase>
<number>tc_arm_idcache</number>
      <use>Yes</use>
</testcase>
<testcase>
<number>tc_arm_icache</number>
      <use>Yes</use>
</testcase>


Read above xml files and arrange the read information (with appropriate conversion, such as converting 32K to 32768) in an excel sheet named, TestInformaiton.xls, in following format.

Test Case No.      Architecture            Cache                                        Usable
                                    ICache Size DCache Size      
tc_arm9_icache      Pace5       32768        4096                      Yes
tc_arm9_dcache      Faraday      16384      4096                       No
tc_arm9_idcache      Pace5      32768      32768                     Yes
tc_arm9_idcache      Pace5      32768      4096                     Yes
tc_arm9_icache      Faraday      4096      16384                    Yes

Thanjks,
Rakesh.

Try this.
This will give you a CSV file.

Thanks
Ned
open  IN, "File1.xml";  #input xml file

open OUT, ">ttt" or die "cannot open output file";

while(<IN>)

{

 if($_ =~/\<(.*)\>(.*)\<(\/*)\1\>/)

 {

  push (@names,$1);

  push(@$1,$2);

  print OUT "$1,$2\n";

   #print "\n$1";

 }

}

close OUT;

close IN;

 

open OUT, ">csvq.csv" or die "cannoo $!";

open IN,"ttt";

print OUT "Name,Architecture,Icachesize,Dcachesize\n";

while(<IN>)

{

chomp();

@a = split/\,/;

$a[1] = 32768 if($a[1] eq '32K');

$a[1] = 16384 if($a[1] eq '16K');

$a[1] = 4096 if($a[1] eq '4K');

if($a[0] eq 'name')

{

$name = $a[1];

$string = $name;

$i=0;

}

else

{

 $string = $string.",".$a[1];

 $i++;

 if($i == 3)

 {

  print OUT "$string\n";

  $i=0;

  $string = $name;

 }

}

 $hash{$a[0]} = 1 if(!$hash{$a[0]});  

}

 

 

foreach (keys % hash)

{

 print "\n headings -> $_" if ($hash{$_}); 

}
