Convert XML to CSV using awk or shell script

Hello,

I am working on a part of code where I need a awk or shell script to convert the given XML file to CSV or TXT file.

There are multiple xml files and of different structure, so a single script is required for converting data.

I did find a lot of solutions in the forum but none of the awk scripts mentioned here work for me as my XML contains Singletags <tag/> too and they are not parsed properly.

Thanks in advance for your help.

Hi! Welcome to Forums,

Please show a representative sample of input, desired output, attempts at a solution and specify what OS and versions are being used.

Thank you.

I have a slightly more capable than average awk tinkertoy parser, which should be able to handle single tags properly, but it will need to be modified for your purposes. It needs to be told which tags to keep and how.

So, please post your input data and the output you want.

Thanks for the reply.

Here is the Sample data:
Code:
<Orders>
<Partner>TTTT</Partner>
<Order>
<OrderType>test</OrderType>
<OrderNumber>1000000000</OrderNumber>
<OrderSource/>
<OrderDate>11/14/2014 12:00:00 AM</OrderDate>
..
..
..
..
<BillingAddress>
<Line1>XXXX</Line1>
<Line2/>
<City>stsss</City>
<State>gg</State>
<PostalCode>101010</PostalCode>
<CountryCode>aaaaa</CountryCode>
<Name>mmmmmm</Name>
</BillingAddress>
<ShippingAddress>
<NumberOfItems>3</NumberOfItems>
<Name>mmmmm</Name>
<Line1>abcd</Line1>
<Line2/>
<City>xyz</City>
<State>sjsdjhi</State>
<PostalCode>101010</PostalCode>
<CountryCode>kkkkkk</CountryCode>
<Method>test</Method>
<tag>False</tag>
</ShippingAddress>
<ShippingAddress>
<NumberOfItems>1</NumberOfItems>
<Name>mmmmm</Name>
<Line1>abcd</Line1>
<Line2/>
<City>xyz</City>
<State>sjsdjhi</State>
<PostalCode>101010</PostalCode>
<CountryCode>kkkkkk</CountryCode>
<Method>test</Method>
<tag>False</tag>
</ShippingAddress>
<Item>
<Name>Item1</Name>
<Quantity>3</Quantity>
<UnitPrice>15.99</UnitPrice>
<Eligible>False</Eligible>
<OrderStatus>test</OrderStatus>
<SKU>5-100000</SKU>
</Item
<Item>
<Name>Item2</Name>
<Quantity>1</Quantity>
<UnitPrice>10.49</UnitPrice>
<Eligible>True</Eligible>
<OrderStatus>test</OrderStatus>
<SKU>5-100001</SKU>
</Item>
</Order>
<Order>
..
</Order>
</Orders>

In the Output I need all the tags as Columns. The output file can be CSV or txt file. With the current script, single close tags are not parsed.

Regards,
Rashmitha

Try thic if it works.

Code:
BEGIN {     FS=",";     OFS = "\n"} NR == 1 {for (i = 1; i <=NF; i++)             tag[i]=$i          print "<abc version=\"3.4.1\" urlbase=\"http://mozilla.com/\" maintainer=\"somebody@mozilla.com\" exporter=\"somebody.else@mozilla.com\">"} NR != 1 {print "   <bug>"          for (i = 1; i <= NF; i++)             print "      <" tag[i] ">" $i "</" tag[i] ">"          print "   </bug>"} END {print "</abc>"}

Okay, you have shown half of what you want.

Now we need the other half -- the output you want.

What you are asking for, "each tag as a column", makes no sense since your data includes many nested, non-tabular things. There'd be a huge amount of duplication at the very least.

"This wont work!", was my first thought.
A technicaly halftruth/incorecctness, but helpfull to create a better image, saying would be:

XML is like a Database, whereas CSV/TXT is a Tablesheet at best.

It is NO problem to make all data from a table into a database,but moving a database into a table, even when there are only 5 entries, is already rather complex. (unless the DB was used as a simple table Smilie)
You need to decide which values/cathegories you want to drop in favor of more important data, OR which values you want to store in another file - if you want to preserve ALL data.
