I assume that you expect a GET parameter like in http://example.com/?hello=true.
Test if it exists:
<xsl:if test="/data/params/url-hello">
…
</xsl:if>
Test if it has a non-empty value:
<xsl:if test="normalize-space(/data/params/url-hello)">
…
</xsl:if>
The same works for Symphony's URL params (but they won't be prefixed with url- like the GET parameters).

How can i test if a param passed by url exist or not ?
