XPath matches(text(), ... ) in Saxon 8.4

Hello, I am using following expression to detect presence of nodes, which have text contents matching a regex: <xsl:if test="//*[matches(text(),'^p')]"> ... When running the XSLT containing the test, I get following message : XPTY0004: A sequence of more than one item is not allowed as the first argument of matches() I've tried the expression with the Altova tools and it works there... Am I doing something wrong ? Thanks, Marian

This will fail if any element has more than one text node, that is, if an element has mixed content, or if it contains comments and processing instructions, or even if it contains inter-element whitespace between its child elements. It's best not to use text() when you want the string-value of an element. If you're looking for a text node that matches a regex, use //text()[matches(., '^p')]. If you're looking for an element whose string value matches the regex (i.e., ignoring comments and PIs), then use //*[matches(., '^p')]. Please don't use Altova's behavior as evidence of anything. Go to the spec.
