I seem to remember Daniel Veillard mentioning that this only happens
with the newer xmlReadFile() functions, but not with xmlParseFile().

I have an example of this in XMLStarlet [1], it's essentially

    xmlNodePtr ctxt_node = ctxt->node; // save original context node

    for (i = 0; i < nodes->nodeNr; i++)
    {
        ctxt->node = nodes->nodeTab[i]; // set new context node
        // get result of XPath expression
        res = xmlXPathConvertString(xmlXPathCompiledEval(xpath, ctxt));
        ...
    }

    ctxt->node = ctxt_node; // restore original context node
