How would I dynamically add a new XML node based on the values of other nodes?

Question

Background: I have an old web CMS that stored content in XML files, one XML file per page. I am in the process of importing content from that CMS into a new one, and I know I'm going to need to massage the existing XML in order for the import process to work properly. Existing XML: true false true false true Desired XML: true false true false true 1,3,5 Question: The desired XML adds the node, with a comma-delimited list of the other nodes that have a "true" value. I need to achieve the desired XML for several files, so what is the best way to accomplish this? Some of my ideas: Use a text editor with a regex find/replace. But what expression? I wouldn't even know where to begin. Use a programming language like ASP.NET to parse the files and append the desired node. Again, not sure where to begin here as my .NET skills are only average.

Answer 1

I would probably use the XmlDocument class in .net, but that's just me because I've never been that fond of regexs. You could then use XPath expressions to pull out the child nodes of each page node, evaluate them, and append a new node at the end of the page children, save the XmlDocument when you are done. Xsl is an option too, but the initial learning curve is a bit painful. There's probably a more elegant way with a regex, but if you are only running it once, it only matters that it works.
