如何使用xmlstarlet选择多个具有相同名称的元素?

问题描述 投票:1回答:1

我有以下xml:

<a>
  <TICKET_LIST>
    <TICKET>
      <NUMBER>182820</NUMBER>
      <DETECTION>
        <IP network_id="173230">192.168.140.61</IP>
        <DNSNAME><![CDATA[local]]></DNSNAME>
        <PORT>80</PORT>
        <SERVICE>CGI</SERVICE>
        <PROTOCOL>tcp</PROTOCOL>
      </DETECTION>
      <VULNINFO>
        <TITLE><![CDATA[HTTP TRACE / TRACK Methods Enabled]]></TITLE>
        <TYPE>VULN</TYPE>
        <QID>12680</QID>
        <SEVERITY>3</SEVERITY>
        <STANDARD_SEVERITY>3</STANDARD_SEVERITY>
        <CVE_ID_LIST>
          <CVE_ID><![CDATA[CVE-2004-2320]]></CVE_ID>
          <CVE_ID><![CDATA[CVE-2010-0386]]></CVE_ID>
          <CVE_ID><![CDATA[CVE-2003-1567]]></CVE_ID>
        </CVE_ID_LIST>
      </VULNINFO>
    </TICKET>
    <TICKET>
      <NUMBER>182957</NUMBER>
      <DETECTION>
        <IP network_id="173230">192.168.200.46</IP>
        <DNSNAME><![CDATA[local]]></DNSNAME>
        <PORT>443</PORT>
        <SERVICE>Web server</SERVICE>
        <PROTOCOL>tcp</PROTOCOL>
      </DETECTION>
      <VULNINFO>
        <TITLE><![CDATA[Web Server Uses Plain-Text Form Based Authentication]]></TITLE>
        <TYPE>VULN</TYPE>
        <QID>86728</QID>
        <SEVERITY>3</SEVERITY>
        <STANDARD_SEVERITY>3</STANDARD_SEVERITY>
      </VULNINFO>
    </TICKET>
  </TICKET_LIST>
</a>

我想将某些数据导出为csv格式。

此代码按预期返回一些数据:

xmlstarlet  sel -T -t -m /a/TICKET_LIST/TICKET  -v "concat(NUMBER,',',DETECTION/IP,',',DETECTION/DNSNAME,',',DETECTION/SERVICE,',',DETECTION/PORT,',',VULNINFO/TITLE,',',VULNINFO/QID)" -n file.xml

但是我也对其余所有数据在同一行上的所有CVE_ID数据感兴趣。

我现在得到的结果是:

182820,192.168.140.61,local,CGI,80,HTTP TRACE / TRACK Methods Enabled,12680
182957,192.168.200.46,local,Web server,443,Web Server Uses Plain-Text Form Based Authentication,86728

预期结果是:

182820,192.168.140.61,local,CGI,80,HTTP TRACE / TRACK Methods Enabled,12680,CVE-2004-2320 CVE-2010-0386 CVE-2003-1567
182957,192.168.200.46,local,Web server,443,Web Server Uses Plain-Text Form Based Authentication,86728

由于存在多个CVE_ID元素,您需要添加另一个匹配-m的匹配项(VULNINFO/CVE_ID_LIST/CVE_ID)。

此外,要使换行符(-n)正确输出,您必须中断嵌套(-b)。

示例...

xmlstarlet sel -T -t -m /a/TICKET_LIST/TICKET -v "concat(NUMBER,',',DETECTION/IP,',',DETECTION/DNSNAME,',',DETECTION/SERVICE,',',DETECTION/PORT,',',VULNINFO/TITLE,',',VULNINFO/QID,',')" -m VULNINFO/CVE_ID_LIST/CVE_ID -v "concat(.,' ')" -b -n file.xml

输出...

182820,192.168.140.61,local,CGI,80,HTTP TRACE / TRACK Methods Enabled,12680,CVE-2004-2320 CVE-2010-0386 CVE-2003-1567
182957,192.168.200.46,local,Web server,443,Web Server Uses Plain-Text Form Based Authentication,86728,

如果您看到xmlstarlet内部使用的XSLT(-C)...,那么命令行可能更有意义。

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:exslt="http://exslt.org/common" version="1.0" extension-element-prefixes="exslt">
  <xsl:output omit-xml-declaration="yes" indent="no" method="text"/>
  <xsl:template match="/">
    <xsl:for-each select="/a/TICKET_LIST/TICKET">
      <xsl:call-template name="value-of-template">
        <xsl:with-param name="select" select="concat(NUMBER,',',DETECTION/IP,',',DETECTION/DNSNAME,',',DETECTION/SERVICE,',',DETECTION/PORT,',',VULNINFO/TITLE,',',VULNINFO/QID,',')"/>
      </xsl:call-template>
      <xsl:for-each select="VULNINFO/CVE_ID_LIST/CVE_ID">
        <xsl:call-template name="value-of-template">
          <xsl:with-param name="select" select="concat(.,' ')"/>
        </xsl:call-template>
      </xsl:for-each>
      <xsl:value-of select="'&#10;'"/>
    </xsl:for-each>
  </xsl:template>
  <xsl:template name="value-of-template">
    <xsl:param name="select"/>
    <xsl:value-of select="$select"/>
    <xsl:for-each select="exslt:node-set($select)[position()&gt;1]">
      <xsl:value-of select="'&#10;'"/>
      <xsl:value-of select="."/>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

请注意,输出的第二行末尾带有,。我认为这不会成为问题,因为CSV行将具有相同数量的列。

如果有问题,您可以使用“ if”(-i)并在处理它们之前检查是否有任何CVE_ID ...

xmlstarlet sel -T -t -m /a/TICKET_LIST/TICKET -v "concat(NUMBER,',',DETECTION/IP,',',DETECTION/DNSNAME,',',DETECTION/SERVICE,',',DETECTION/PORT,',',VULNINFO/TITLE,',',VULNINFO/QID)" -i VULNINFO/CVE_ID_LIST/CVE_ID -o "," -m VULNINFO/CVE_ID_LIST/CVE_ID -v "concat(.,' ')" -b -n file.xml

输出与上面相同,除了第二行未输出尾随, ...

182820,192.168.140.61,local,CGI,80,HTTP TRACE / TRACK Methods Enabled,12680,CVE-2004-2320 CVE-2010-0386 CVE-2003-1567
182957,192.168.200.46,local,Web server,443,Web Server Uses Plain-Text Form Based Authentication,86728
