Ruby XML Replacing

I have an XML file, and I need to replace the text between two tags with a new string the tags are <<Connecti开发者_运维百科onString>ConnectionString>THE OLD TEXT<<ConnectionString>/ConnectionString>

I need to change this to <<ConnectionString>ConnectionString>MY NEW TEXT<<ConnectionString>/ConnectionString>

I can't seem to find anything online, and see that using regex is a bad idea?

Please note, that this file contains more that 1

<<ConnectionString>ConnectionString>THE OLD TEXT<<ConnectionString>/ConnectionString>

Lines!

Can someone point my in the right direction or an example? Andrew

Nokogiri is great for things like this. See the Nokogiri::Node#content= method

#!/usr/bin/env ruby

require 'nokogiri'

doc = Nokogiri.XML(DATA)             # create a new nokogiri object, this could be a string or IO type (anything which responds to #read)
element = doc.at('ConnectionString') # fetch our element
element.content = "MY NEW TEXT"      # change the content
puts doc #=> <?xml version="1.0"?>\n<ConnectionString>MY NEW TEXT</ConnectionString>


__END__
<ConnectionString>THE OLD TEXT</ConnectionString>

Use nokogiri for dealing with XML files. See this for the specific task.

I agree in general to use nokogiri over regex in xml but in this case I think it's overkill.

xml = open(xmlfile).read.gsub /<ConnectionString>THE OLD TEXT<\/ConnectionString>/, '<ConnectionString>MY NEW TEXT</ConnectionString>'
