我使用xmlstarlet el -v来显示xml文件的结构,包括所有属性和值.我想将其输出转换为某种键值对,即每个属性的值在一个单独的行上(包括XPath);每一行必须是唯一的.
目前的结果：
topRoot/topSystem/commSvcEp/commSyslog[@descr='Syslog Service' and @name='syslog' and @policyOwner='local' and @severity='critical'] topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[@adminState='disabled' and @forwardingFacility='local7' and @hostname='none' and @name='secondary' and @severity='critical'] topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[@adminState='disabled' and @forwardingFacility='local7' and @hostname='none' and @name='tertiary' and @severity='critical'] topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[@adminState='disabled' and @forwardingFacility='local7' and @hostname='none' and @name='primary' and @severity='critical']
期望的结果(可能是类似的;指数只是一个想法)：
topRoot/topSystem/commSvcEp/commSyslog@descr='Syslog Service' topRoot/topSystem/commSvcEp/commSyslog@name='syslog' topRoot/topSystem/commSvcEp/commSyslog@policyOwner='local' topRoot/topSystem/commSvcEp/commSyslog@severity='critical' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[0]@adminState='disabled' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[0]@forwardingFacility='local7' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[0]@hostname='none' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[0]@name='secondary' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[0]@severity='critical' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[1]@adminState='disabled' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[1]@forwardingFacility='local7' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[1]@hostname='none' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[1]@name='tertiary' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[1]@severity='critical' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[2]@adminState='disabled' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[2]@forwardingFacility='local7' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[2]@hostname='none' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[2]@name='primary' topRoot/topSystem/commSvcEp/commSyslog/commSyslogClient[2]@severity='critical'
我想要完成的是能够在两个这样的文件上运行diff或使用grep来过滤匹配的模式.我确信有一种方法可以创建这样的输出,而不使用sed,awk或其他任何东西,但xmlstarlet本身.
我几乎是关于xmlstarlet和整个xml世界的新手(不仅因为它因为它的复杂性和解析开销等而不喜欢xml),所以我非常感谢你的帮助.谢谢！
由于您已经在使用xmlstarlet,因此您也可以使用XSLT.
原文链接：https://www.f2er.com/xml/292090.htmlXSLT 1.0(可以使用tr命令使用xmlstarlet运行)
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:strip-space elements="*"/>
<xsl:param name="sep" select="'.'"/>
<xsl:template match="text()"/>
<xsl:template match="*">
<xsl:variable name="path">
<xsl:for-each select="ancestor-or-self::*">
<xsl:variable name="predicate">
<xsl:call-template name="genPredicate"/>
</xsl:variable>
<xsl:if test="ancestor::*">
<xsl:value-of select="$sep"/>
</xsl:if>
<xsl:value-of select="concat(local-name(),$predicate)"/>
</xsl:for-each>
</xsl:variable>
<xsl:for-each select="@*">
<xsl:value-of select="concat($path,$sep,name(),'=',.)"/>
<xsl:text>
</xsl:text>
</xsl:for-each>
<xsl:if test="not(@*)">
<xsl:text>
</xsl:text>
</xsl:if>
<xsl:apply-templates select="node()"/>
</xsl:template>
<xsl:template name="genPredicate">
<xsl:if test="preceding-sibling::*[local-name()=local-name(current())] or following-sibling::*[local-name()=local-name(current())]">
<xsl:value-of select="concat('[',count(preceding-sibling::*[local-name()=local-name(current())])+1,']')"/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
注意：有一个名为sep的参数,因此您可以从命令行更改分隔符(使用-p sep =“/”或您想要的任何分隔符).它目前设置为您首选的“.”.
