In XSLT 2.0 the rule is:

* the delimiter of the XML attribute can be escaped as & quot; or & apos;
respectively

* the delimiter of the string literal can be escaped by doubling it.

However, a simpler approach is often to put the regex in a variable:

<xsl:variable name="regex" as="xs:string">['"](.*?)["']</xsl:variable>

<xsl:value-of select="matches(, $regex)"/>

This way, neither quotes nor apostrophes need to be escaped.
