These are 2 completely different things:

• XQL and QL are two of many (and I mean _many_) proposals to W3C for XML query languages: languages to query XML documents (which could be flat files but more likely stored in an XML data base). The result of a query is a list of documents or fragments of documents. As long as you stay within a single document XML::XPath is probably your best choice, it implements XPath, a query language limited to a single document, and DOM-style transformation. BTW as far as I know both XML::QL and XML::XQL are also limited to searching a single document, but that's an implementation choice, not a design choice as for XML::XPath.
• what you are describing is a way to include data from a relational data base into an XML document. You put special XML tags in your document and a piece of software later replaces those tags by the appropriate data, properly tagged. If you want to import the result of XML queries into a document you can have a look at DBIx::XML_RDB, couple it with XML::PYX, or any other XML processing module, and you can get what you seem to describe fairly easily. It will probably be a little slower to write and slower to run than what Oracle offers but it will be much more portable.

Just don't confuse XML query languages and embedding SQL statement into an XML document.
