Любые идеи, что я делаю неправильно

Answer 1

Ошибка в строке 15 очевидна:

<xsl:value-of select="$delimiter/> 

Там не является исходным " характер, но не заканчивается " характер. Это даже не хорошо сформированный XML-документ.

Решение: заменить строку, которая является ошибкой с:

<xsl:value-of select="$delimiter"/> 

Примечание, что теперь о том, " имеет согласование окончание ".
