Here is an example of how to do it using xsltproc. Suppose your XML document (file.xml) contains 2 records i.e.
Code:
<?xml version = "1.0"?>
<root>
<eq action="A" sectyType="0" symbol="PGR" exch="CA" curr="VEF" sess="NORM" dfltInd="1" issuerName="PROAGROI-7 B" issuSho
rtDesc="VEB100" sectySubType="" sedol="2705132" isin="VEV000901000" cusip="" localCode="VEV000901000" localId="5" Csymbo
l="PGR" Cexch="CA" Ccurr="VEF" Csess="NORM" Psymbol="PGR" Pexch="CA" Pcurr="VEF" Psess="NORM" Ssymbol="PGR" Sexch="CA" S
curr="VEF" Ssess="NORM" exclPFInd="0" ranking="" longIssuerName="PROAGRO, C.A." issuLongDesc="VEB100" sicCode="" exchSym
="" streetSym="" mostLiquid="0" />
<eq action="A" sectyType="0" symbol="PGR" exch="BB" curr="VEF" sess="NORM" dfltInd="1" issuerName="PROAGROI-8 B" issuSho
rtDesc="VEB100" sectySubType="" sedol="2705132" isin="VEV000901000" cusip="" localCode="VEV000901000" localId="5" Csymbo
l="PGR" Cexch="CA" Ccurr="VEF" Csess="NORM" Psymbol="PGR" Pexch="CA" Pcurr="VEF" Psess="NORM" Ssymbol="PGR" Sexch="CA" S
curr="VEF" Ssess="NORM" exclPFInd="0" ranking="" longIssuerName="PROAGRO, C.A." issuLongDesc="VEB100" sicCode="" exchSym
="" streetSym="" mostLiquid="0" />
</root>

and you have an XSL stylesheet called file.xsl (deliberately simplified) which contains
Code:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>

<xsl:template match="/">
  <xsl:apply-templates select="/root/eq"/>
</xsl:template>

<!-- write out comma separated file -->
<xsl:template match="/root/eq">
   <xsl:value-of select="@issuerName"/>
   <xsl:value-of select="','"/>
   <xsl:value-of select="@symbol"/>
   <xsl:value-of select="','"/>
   <xsl:value-of select="@exch"/>
   <xsl:value-of select="','"/>
   <xsl:value-of select="@curr"/>
   <xsl:value-of select="','"/>
   <xsl:value-of select="@Csymbol"/>
   <xsl:value-of select="','"/>
   <xsl:value-of select="@Cexch"/>
   <xsl:value-of select="','"/>
   <xsl:value-of select="@Ccurr"/>
   <xsl:text>
</xsl:text>
</xsl:template>

</xsl:stylesheet>

Using xsltproc to transform the document produces the required output
Code:
$ xsltproc file.xsl file.xml
PROAGROI-7 B,PGR,CA,VEF,PGR,CA,VEF
PROAGROI-8 B,PGR,BB,VEF,PGR,CA,VEF

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
