XQuery: Inserting Nodes

Question

I'm reading in an XML file using XQuery and want to insert several nodes/elements and generate a new XML file. How can I accomplish this?

I've tried using the replace() function, but, it looks like all my XML tags are being stripped when I call doc() to load my document. So calling replace() isn't any good if my XML tags are being removed.

Any help? Are there other technologies I can use?

Answer 1

It would be useful to know what XQuery implementation you are using.

Answer 2

replace() is a string operation, so the XML will be converted to a string before replacement.

To create a modified copy of the original file, you can modify an identity transformation which recursively copies the original file to insert the new nodes where required - see the article in the XQuery Wikibook

Alternatively if the file is in an XML database such as eXist, you can use update operations to insert elements in situ.
