Not knowing how to write a reader or a serializer I think I'm going to have to run a
batch process, something like the following in BASH/Perl and sabletron (because it was
installed.)
DIR=/usr/local/jakarta-tomcat-3.3.1/webapps/cocoon/content
ls $DIR/*.xml > /tmp/xmlfiles
for i in `cat /tmp/xmlfiles`
do
sabcmd $DIR/base64tiff.xsl $i $i.64tiff
perl -MMIME::Base64 -ne 'print decode_base64($_)' <$i.64tiff
>$i.tiff
convert $i.64tiff $i.jpg
done
My stylesheet -simple
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
<xsl:value-of
select="//ContentItem/Encoding[@Notation='base64']/DataContent"/>
</xsl:template>
</xsl:stylesheet>
However, all of my tiff base64 files have <?xml version="1.0" encoding="UTF-8"?>
prepended to them - I'm curios as to wether or not their is a way to avoid this at the
top of xsl processed files using standard xslt techniques?
