How do I "pass" (POST/GET??) a jQuery selection set from one page to another?

Specifically, I'm talking about passing an XML node, but the process would be the same for passing a <div> tag and its contents, right?
On the first page, I use jQuery to parse an XML file, then when the user clicks a link, I want to pass a reference to a child XML node (depending on which link they click) to the 2nd page.
Then, the 2nd page will have some jQuery that will parse the child node.
