RSS Parser Help..

[Gim Ick]

I am trying to parse a rss file. I use the rss module to do it.

Suppose this is the data file,

<item>
<title>Singapore Airlines Asia Travel - A345 All Business Class to
Asia</title>

<category

<category
domain="http://delicious.com/galvezcreative/">marketing</category>
</item>

How do I parse to get value in category( In the above example it is
Industry-Airlines and marketing).

When i try rss.items[0].category , I get the entire element( In the
above case, <category
domain="http://delicious.com/galvezcreative/">Industry-Airlines</category>)

How do I parse to get value in category( In the above example it is

rss.items[0].categories.each do |category|
p category.content
end

When i try rss.items[0].category , I get the entire element( In the
above case, <category
domain="http://delicious.com/galvezcreative/">Industry-Airlines</category>)

rss.items[0].category returns Category object not "<category
...>...</category>" string. (Hint: Category object has #to_s
method that returns "<category ...>...</category>" string)

Thanks,

Thanks! I was using regular expressions to do this task!

Alternate biterscripting script.

# Script category.txt
var str rss ; cat "file.rss" > $rss
while ( { sen -r -c "^^" $rss } > 0 )
do
var str category ; stex -r -c "^<category&\>&</category\>^" $rss >
$category
stex -r -c "^<category&\>^]" $category > null ; stex -r -c "[^</
category\>^" $category > null
echo $category
done


For documentation on stex (string extractor) command, see
