XML PARSING of dynamic xml file to flat file

sandip has asked for the wisdom of the Perl Monks concerning the following question:

In xml file i have following data where some tags like<ChrgBr> may not be present in every next file. So i want these values to be stored in some variable like var1="405360,00" , var2="DEBT" and so on ,but if <ChrgBr> tag has no value or is absent var2 should have space like var2=" " so that i can put the if condition to print only present varable values in the flat file

SAMPLE DATA XML FILE:1

<IntrBkSttlmAmt Ccy="USD">405360,00</IntrBkSttlmAmt>
<ChrgBr>DEBT</ChrgBr>
<ChrgsInf>
<Amt Ccy=>00.00</Amt>
<Agt>
<FinInstnId>
<ClrSysMmbId>
<MmbId>BRANCHNO1</MmbId>
</ClrSysMmbId>
</FinInstnId>
</Agt>
</ChrgsInf>
<c>

SAMPLE DATA XML FILE :2

Hi, I'm not pretty sure what you want to ask us? Do you have some code, that doesn't work as you thought it should? Or do you want us to present a parsing solution for your problem? My solution in pseudocode: `- initialize variable to '' - Look at xml whether corresponding xml tag is present - if yes, than take the value into your variable` [download] Please be more specific.

Look at the Super Search facility of perlmonks. You will find so much stuff about XML parsing. Have a look at XML::Twig as one of the top rated modules. Best regards McA	[reply]
