xsl param default string cannot start with period

Question

In my stylesheet I try to set the default value for an input parameter to a string beginning with the dot character. And always receive an error code 0x8004005 - Expected toden 'eof' found 'NAME'. For example:

<xsl:param name="p1" select=".exe"/>

However it doesn't matter what follows the dot. Always same error. How do I form this string to include the first dot?

Answer 1

You need to specify the "default value" as a string literal.

Simply change:

<xsl:param name="p1" select=".exe"/>

to:

<xsl:param name="p1" select="'.exe'"/>

In the former case the value of the select attribute is evaluated as an XPath expression -- not as a string.
