It's possible if you remove the curly braces:

<xsl:variable name="textContent" select="$dynamicPath/text()"/>

AVTs are not valid in XPath expressions.

btw, based on your input XML, $textContent is redundant; if you use
$dynamicPath in xsl:value-of, the result will be identical, since value-of
writes the string value of the expression to the result tree.
