HI,

Thanks for the help.

i have a xml and want to parse it line by line. suppose i have
abc = "<a1>
       <a2>123</a2>
       <a3>123</a2>
       <a4>123</a2>
       <a5>123</a2>
       </a1>"

and i want to parse it line by line. there could be any number of line.
my output should be seperate string like
"<a1>"
"<a2>123</a2>"
"<a3>123</a3>"
"<a4>123</a4>"
"<a5>123</a2>"
"</a1>"

how can i acheive this one using any string function or regular
expression.

Please help.

Thanks
Saurabh

If you just want to split string by lines, abc.split(/\r?\n/) should
do the trick.

If what you actually want is to parse the XML data, I suggest using an
actual XML parser - Nokogiri, if you are doing some heavy lifting, or
xml-simple for, well, simple things.

Hello,

give the following a try.

str = "<note>\n<to>Tove</to>\n<from>Jani</from>\n<heading>Reminder</heading>\n<body>Don't forget me this weekend!</body>\n</note>"
str.each_line { |s| puts s }

Thanks
Josh

Hello,

Sry I forgot to add the each on the end

Please try this following instead
str = "<note>\n<to>Tove</to>\n<from>Jani</from>\n<heading>Reminder</heading>\n<body>Don't forget me this weekend!</body>\n</note>"
str.each_line.each { |s| print s.strip }

I simply use the each_line to get and enumerator then call the each method on that. Then inside the block make sure to strip the '/n' of course you can do as you wish inside the block.

Thanks
Josh
