我正在尝试编写xslt文件，该文件将检查server.xml的SSL配置。
由于我们有多个“构造函数”元素但无法成功设置变量，因此我找到了一种方法来设置一个变量，如果没有找到配置，我已经浪费了两天。请告诉我如何实现我的需要。
server.xml是;
<?xml version='1.0' encoding='utf-8'?>
<?xml-stylesheet type="text/xsl" href="new2.xsl"?>

和已编辑 xslt是;

<!-- Add the missing Connector here -->

</xsl:template>

以上xslt适用于所有场景，除非在找不到新元素时添加新元素，它在</Service>结束标记之前添加Connector元素，但在<Service>之前需要它<Engine>开头标记以及其他连接器元素
谢谢。

如果没有匹配的连接器，则应该取消注释所需的连接器，如果不存在，则应该添加新的连接器：
