sed를 사용하여 xml 파일의 내용을 주석 처리하는 방법은 무엇입니까?

노력하다:

sed '{$!{N;s/<Valve.*\n.*allow.* \/>/<!-- & -->/;ty;P;D;:y}}' content.xml

다음과 같이 출력됩니다.

...
<Context antiResourceLocking="false" privileged="true" >
  <!-- <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" /> -->
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

필요한 경우 주석 레이블을 별도의 줄에 배치하도록 쉽게 수정할 수 있습니다.

sed '{$!{N;s/<Valve.*\n.*allow.* \/>/<!--\n&\n-->/;ty;P;D;:y}}' content.xml

이 시도:

sed -r '/^\s*<Valve className\s*=\s*"org\.apache\.catalina\.valves\.RemoteAddrValve"\s*$/{h;z;N;s:^\n::;H;/^\s*allow\s*=\s*"127\\\.\\d\+\\\.\\d\+\\\.\\d\+\|::1\|0:0:0:0:0:0:0:1"\s*\/>\s*$/{g;s/.*/<!--\n&\n-->/}}' context.xml

XSL 변환과 함께 xsltproc또는 를 사용하십시오 .xmlstarlettransform.xsl

<?xml version="1.0"?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

  <xsl:template match="/|node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="/Context/Valve">
    <xsl:text disable-output-escaping="yes">&lt;!-- </xsl:text>
    <xsl:copy-of select="."/>
    <xsl:text disable-output-escaping="yes"> --&gt;</xsl:text>
  </xsl:template>

</xsl:transform>

첫 번째 템플릿은 단지 항등 변환인 반면, 두 번째 템플릿은 노드 주위에 합계를 삽입합니다 <!--.-->/Context/Valve

노드에 있는 속성의 정확한 값을 일치시켜야 하는 경우 match두 번째 템플릿에서 보다 구체적인 XPath 쿼리를 사용하여 이를 수행합니다.

<xsl:template match="/Context/Valve[
      @className='org.apache.catalina.valves.RemoteAddrValve' and
      @allow='127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1'
]">

xmlstarlet tr transform.xsl file.xml적용은 다음을 사용하여 수행할 수 있습니다 xsltproc transform.xsl file.xml.

$ xsltproc transform.xsl file.xml
<?xml version="1.0"?>

이는 형식에 관계없이 노드 주석 처리를 처리합니다.

변경되지 않는 정적 파일인 경우 올바른 줄에 주석 태그를 삽입하세요.

sed '17s/^/<!-- /; 18s/$/ -->/' file.xml
