如何编写一个bash脚本，它可以解析XML文件作为输入并从文件中删除某些元素

I need to create a bash script that manipulates the following sample xml file:

我需要创建一个操作以下示例xml文件的bash脚本:

check for a particular ID and remove that XML branch for that ID.

检查特定ID并删除该ID的XML分支。

the ID's are read from a text file.

ID是从文本文件中读取的。

<?xml version="1.0"?>
<cmtf xmlns="urn:RM_UPMS_CMTFEnvelopeSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<data xmlns="">
<entitygroup entityname="people">
  <PERSON xmlns="abc">
    <ID ns="">12280</ID>
    <PIN xmlns="">erererre</PIN>
    <NAME xmlns="">ereffdef</NAME>
  </PERSON>
  <PERSON xmlns="bbc">
    <ID ns="">5567</ID>
    <PIN xmlns="">erererre</PIN>
    <NAME xmlns="">ereffdef</NAME>
  </PERSON>
  <PERSON xmlns="bbc">
    <ID ns="">3347</ID>
    <PIN xmlns="">ededed</PIN>
    <NAME xmlns="">rtreer</NAME>
  </PERSON>
  <PERSON xmlns="bbc">
    <ID ns="">3249</ID>
    <PIN xmlns="">erererre</PIN>
    <NAME xmlns="">ereffdef</NAME>
  </PERSON>
</entitygroup>
</data>
</cmtf>

Here, I need to remove all the <PERSON> tag for all the entries that have the ID 12280, 3249 which is being read from a text file.

在这里,我需要删除所有从文本文件中读取ID为12280,3249的条目的标记。

Perhaps you could use php like this: running php script (php function) in linux bash

也许你可以使用这样的php:在linux bash中运行php脚本(php函数)

And then you something like domdocument(http://php.net/manual/en/class.domdocument.php) to read and the right the xml.

然后你就像domdocument(http://php.net/manual/en/class.domdocument.php)来读取和正确的xml。

Of course this is assumes you have php installed.

当然这是假设你安装了php。

You can use XSLT for that. Create an xsl stylesheet which transform the input xml into the desired output. On the console you can use xsltproc (from xmllint package):

您可以使用XSLT。创建一个xsl样式表,将输入xml转换为所需的输出。在控制台上,您可以使用xsltproc(来自xmllint包):

 xsltproc stylesheet.xsl input.xml

#3

This reads a series of IDs to delete from a file input_file, and creates an output.xml based on input.xml with those entries deleted:

这将读取要从文件input_file中删除的一系列ID,并基于input.xml创建一个output.xml,并删除这些条目:

ed_commands=( )
while read -r num_to_delete; do
  ed_commands+=( -d "//PERSON[./ID=$num_to_delete]"
done <input_file

xmlstarlet ed "${ed_commands[@]}" <input.xml >output.xml

Note that it requires XMLStarlet.

请注意,它需要XMLStarlet。
