Parse XML file into CSV with shell?
Hi,

It's been a few years since college when I did stuff like this all the time. Can someone help me figure out how to best tackle this problem? I need to parse a file full of entries that look like this:

<eq action="A" sectyType="0" symbol="PGR" exch="CA" curr="VEF" sess="NORM" dfltInd="1" issuerName="PROAGROI-7 B" issuShortDesc="VEB100" sectySubType="" sedol="2705132" isin="VEV000901000" cusip="" localCode="VEV000901000" localId="5" Csymbol="PGR" Cexch="CA" Ccurr="VEF" Csess="NORM" Psymbol="PGR" Pexch="CA" Pcurr="VEF" Psess="NORM" Ssymbol="PGR" Sexch="CA" Scurr="VEF" Ssess="NORM" exclPFInd="0" ranking="" longIssuerName="PROAGRO, C.A." issuLongDesc="VEB100" sicCode="" exchSym="" streetSym="" mostLiquid="0" />

And I want the data in a csv file with the following columns:

issuerName (symbol-exch) | symbol | exch | curr | Csymbol | Cexch | Ccurr

I only want the data that's in each of these fields, so I want PGR, not symbol="PGR"

I can use sed to strip away everything but the data I need -- which I've done -- but the data remains in its original order, not the one I'm looking for: (Note, the issuerName field is in Brackets for visual purposes).

PGR CA VEF [PROAGROI-7 B] PGR CA VEF

What's the best way to re-order the above line according to my CSV needs? Or is there a different approach I should be taking entirely?

kvm_nlist

KVM_NLIST(3)						   BSD Library Functions Manual 					      KVM_NLIST(3)

NAME

     kvm_nlist -- retrieve symbol table names from a kernel image

LIBRARY

     Kernel Data Access Library (libkvm, -lkvm)

SYNOPSIS

     #include <kvm.h>
     #include <nlist.h>

     int
     kvm_nlist(kvm_t *kd, struct nlist *nl);

DESCRIPTION

     The kvm_nlist() function retrieves the symbol table entries indicated by the name list argument nl.  This argument points to an array of
     nlist structures, terminated by an entry whose n_name field is NULL (see nlist(3)).  Each symbol is looked up using the n_name field, and if
     found, the corresponding n_type and n_value fields are filled in.	These fields are set to 0 if the symbol is not found.

     The kldsym(2) system call is used to locate the symbol.  This is a less than perfect emulation of the nlist values but has the advantage of
     being aware of kernel modules and is reasonably fast.

RETURN VALUES

     The kvm_nlist() function returns the number of invalid entries found.  If the kernel symbol table was unreadable, -1 is returned.

SEE ALSO
