Unix中的腳本從文件中刪除XML標記和內容

Question

基本上需要從由number.xml命名的一組單個XML文件中刪除當事方實體（以及它們之間的所有內容）。我嘗試以下，但它並不完全生產我需要的一切：

cat test.xml | sed "s;<parties>;\do_opentag ;" | sed "s;</parties>;\do_closetag ;" | awk 'BEGIN { doPrint = 1; } /do_opentag/ { doPrint = 0; print $0; } /do_closetag/ { doPrint = 1; } { if (doPrint) print $0; }' | grep -v 'do_opentag\|do_closetag'

Answer 1

解析XML 需要 XML解析器。 xmlstarlet使用起來相當簡單。要刪除parties節點：

xmlstarlet ed -P -d '//parties' file.xml 

產生

<?xml version="1.0" encoding="UTF-8"?> 
<patent-document xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" pid="58326519" doc-generation-date="2016-10-11">

    <publication-reference> 
     <publication-office>KR</publication-office> 
     <patent-publication-date> 
     <year>2016</year> 
     <month>10</month> 
     <day>11</day> 
     </patent-publication-date> 
    </publication-reference> 

    </bibliographic-data> 
    <vendor>Any</vendor> 
    <document-translation-date>2016-11-24</document-translation-date>M 
    <invention-title lang="EN">Cell preservation container for liquid-based cell inspection</invention-title> 
    <abstract lang="EN">The present invention relates to a liquid for discharging liquid containing cells and cell may be a sampling which is simply eminent generated in </abstract>

Answer 2

sed -e '/<parties>/,/<\/parties>/d' test.xml

在sed可以使用由逗號分隔的兩個圖案施加sed命令或命令行的包括該範圍和匹配模式之間。我在這裏說d - 刪除行 - 從/<parties>/到/<\/parties>/。

這取決於您的XML格式。在匹配行上不能有其他內容需要保留。

如果要編輯文件，請將一個-i標誌添加到sed。
