Question

我有一个包含以下内容的XML文件 -

<File Name="something.txt" >
 <EmailWhenMissing>Customer</EmailWhenMissing>
 <CustomerEmail>somebody@email.com</CustomerEmail>
</File>
<File Name="somethingElse.txt" >
 <EmailWhenMissing>Customer</EmailWhenMissing>
 <CustomerEmail>somebodyelse@email.com</CustomerEmail>
</File>

是否有任何方法或最佳方式遍历每个<File>元素，以便我可以单独执行命令？（即，以便我能够识别哪些文件标签有空白或缺少元素）

Answer 1

您可以使用xmlstarlet

for f in $(xmlstarlet select -t -v '//File/@Name' file.xml)
do
   echo $f
done

Answer 2

如果我正确理解您的目标是验证每个File中的字段，请将以下内容视为相关示例：

#!/bin/bash
#      ^^^^- IMPORTANT: not /bin/sh

sep=$'\v' # pick a character that can't be in your data

while IFS="$sep" read -r Name EmailWhenMissing CustomerEmail; do
  # the line below this provides verbose logging when running with bash -x
  : Name="$Name" EmailWhenMissing="$EmailWhenMissing" CustomerEmail="$CustomerEmail"
  [[ $EmailWhenMissing ]] || { echo "File $Name is missing EmailWhenMissing"; }
  [[ $CustomerEmail ]] || { echo "File $Name is missing CustomerEmail"; }
done < <(xmlstarlet sel -t -m '//File' \
           -v ./@Name -o "$sep" \
           -v ./EmailWhenMissing -o "$sep" \
           -v ./CustomerEmail -n)

给出以下输入文件：

<root>
  <File Name="something.txt">
    <EmailWhenMissing>Customer</EmailWhenMissing>
    <CustomerEmail>somebody@email.com</CustomerEmail>
  </File>
  <File Name="somethingElse.txt">
    <EmailWhenMissing>Customer</EmailWhenMissing>
    <CustomerEmail>somebodyelse@email.com</CustomerEmail>
  </File>
  <File Name="NoEmailWhenMissing.txt">
    <CustomerEmail>somebodyelse@email.com</CustomerEmail>
  </File>
  <File Name="NoCustomerEmail.txt">
    <EmailWhenMissing>Customer</EmailWhenMissing>
  </File>
  <File Name="EmptyFile.txt"/>
</root>

......其输出是：

File NoEmailWhenMissing.txt is missing EmailWhenMissing
File NoCustomerEmail.txt is missing CustomerEmail
File EmptyFile.txt is missing EmailWhenMissing
File EmptyFile.txt is missing CustomerEmail

关于这里的bash代码，一些有用的阅读：

使用bash迭代XML标记
