我正在尝试编写xslt文件，该文件将检查server.xml中的SSL配置。
- 如果SSL配置已经存在，则保持原样。
- 即使注释部分也在那里，也不应该取消注释(否则会有两个SSL配置)，因为SSL配置已经可用。
- 如果SSL配置部分被注释，取消注释。
- 如果没有注释部分，我们应该自己设置SSL配置。
我浪费了两天的时间来寻找一种方法来设置一个变量，如果没有找到配置，因为我们有多个"构造函数"元素，但无法成功设置变量。请告诉我怎样才能达到我所需要的。
server.xml是;

和编辑 xslt从JLRishe下面的回答是;
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="comment()[not(../Connector[@scheme = 'https']) and
contains(., 'Connector') and
(contains(., 'scheme=https') or
contains(., scheme='https'))]">
<xsl:value-of select="." disable-output-escaping="yes" />
</xsl:template>
<xsl:template match="Service[not(Connector[@scheme = 'https'] or
comment()[contains(., 'Connector') and

<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
<!-- Add the missing Connector here -->
<xsl:element name="Connector">

上面的xslt只适用于所有场景，除了添加新元素，当没有发现时，它是在</Service>结束标记之前添加Connector元素，但在<Service>中需要在<Engine>开始标记之前与其他Connector元素
谢谢。
