Are you trying to output all fields in this XML formatted document to CSV?

Yes, i am trying to get all the fields.

What XSLT transform you using? What language (i.e Java, Perl, .NET, etc..)?

I am using Java, but as an initail conversion i am using XML Spy to do the conversion. Your hep will be of great use.

How do you handle the AddressableElement ? In your example there are two. Are there always two and appear both on one line ? Or are other situations possible.

Anyway, start with this:

<xsl:template match="Transaction">
  <xsl:value-of select="@TransactionID" disable-output-escaping="yes" />,
  <xsl:value-of select="@EventDate" disable-output-escaping="yes" />,
</xsl:template>

Thanks for your response @Pritaeas.

The AddressableElement tag may be 1/2/3 depending on the data, so no fixed thing that it would come in. Same is the case with the Capability tag.

[nvishwas]

I meant AddressableElement would be repeated multiple times but not greater than 3 times.
