Store XML format data into database

Hi all,

I am making application in Rails 3 in which I am parsing XML file and I
want to store one of the XML tag in XML format into Mysql database. I
have used ‘TEXT’ as a datatype to store XML formatted data.

I am getting the XML format Tag data but when I store it into database I
am getting an error.

Can any one please help me that how can I store XML data into database?

Thanks

Show us the full error and stack trace please. Also a few lines of
code around the error.

Hi,

Now I am not getting an error but XML values are stored like ‘–0 \n’.

Code is:

doc.xpath(’//item’).each do |tag|
@req = Hash.new
@req = tag.children[9]

   detail.create(
      :my_field => tag.children[9]
   )

end

And in detail_model.rb

class Detail < ActiveRecord::Base
serialize :my_field
end

Hi,

Thanks for the reply… When I puts tag.children[9] like this:

doc.xpath(’//item’).each do |tag|
puts tag.children[9]
@req = Hash.new
@req = tag.children[9]

detail.create(
  :my_field => tag.children[9]
)

end

I am getting the whole XML Tag. But this tag is not saving into the
database. It is saving like ‘–0 \n’. Is there any problem with my model
or Datatype into the database??

Thanks

I think you’ll find that tag.children[9] is just an object
representing the node, which doesn’t have much meaning without the
document it belongs to. You need to call something like to_s or to_xml
on it to turn it back into a string

Have you used ruby-debug to break into the code here and see what
tag.children[9] looks like? Have a look at the Rails Guide on
debugging to see how to do this.
