XSLT的默认行为是忽略样式表中完全为空格的任何文本节点(即使某些空格被编码为类似于)，但保留<xsl:text>中的文本.

XSLT's default behavior is to ignore any text nodes in the stylesheet that are entirely whitespace (this is true even if some of the whitespace is encoded as entities like 
), except for text inside <xsl:text>, which is preserved.

我建议替换这些行:

<xsl:value-of select="ApplicationID"/>,<xsl:value-of select="USERID"/>
&#10;

与此:

<xsl:value-of select="concat(ApplicationID, ',', USERID, '&#10;')"/>

这样，应确保换行符包含在输出中.

That way the newline should be ensured to be included in the output.
