我有一个文本文件，我使用以下批处理代码提取所需的部分：

@echo off > newfile & setLocal enableDELAYedeXpansioN

set H=
set T=
for /f "tokens=1* delims=[]" %%a in ('find /n "<face>" ^< C:\XML\INTERM\image-0000001.txt') do (
set H=%%a
)
for /f "tokens=1* delims=[]" %%a in ('find /n "</face>" ^< C:\XML\INTERM\image-0000001.txt') do (
set T=%%a
)
for /f "tokens=1* delims=[]" %%a in ('find /n /v "" ^< C:\XML\INTERM\image-0000001.txt') do (
if %%a gtr !H! if %%a lss !T! echo.%%b
)>> c:\XML\ADD\image-0000001.txt
goto :eof

我的结果文本文件是：

我需要从x，y，width和height（不是LinearRing ptCount="36"）的双引号之间提取每个数字，将每个数字相乘2并逐一回写。我必须提到Point标签的数量（在这种情况下是36）可能会有所不同。我的操作系统是Windows 10。

这是一个依赖JREPL.BAT的“简单”快速解决方案。它完全取代了整个脚本。

@echo off
setlocal
set "input=C:\XML\INTERM\image-0000001.txt"
set "output=c:\XML\ADD\image-0000001.txt"

jrepl "<face>([\s\S]*)</face>" $1 /m /jmatch /f "%input%" | ^
jrepl "((?:x|y|width|height)=\q)([^\q]*)(\q)" "$txt=$1+(Number($2)*2)+$3" /x /jq /o "%output%"

但实际上你应该使用一个专门用来处理XML文件的工具。

这是一个纯粹的解决方案，可以以非常缓慢的方式完成您想要的任务。

以下限制适用：

  • 将XML文件视为“普通”文本文件;
  • 该文件必须是ANSI编码的;
  • 该文件必须是Windows文本文件（行尾标记为回车加行换行）;
  • 空行丢失;
  • 行不得超过约8190个字符/字节;
  • 感兴趣的代码（Point，Rectangle）必须各自各自;
  • 感兴趣的标签必须像<Point/>;不允许使用<Point>，</Point>之类的内容;
  • 标签名称以及属性名称（x，y，width，height）必须完全匹配大小写;
  • 属性值必须是（带符号）浮点数（不允许指数格式）;
  • 将浮点数舍入为不超过八位小数;
  • 浮点数的绝对值必须小于10 8 ;
  • 将浮点数乘以的整数因子不得超过21的值;
  • 返回的结果（相乘）浮点数恰好是八位小数;

所以这是代码：

@echo off
setlocal EnableExtensions DisableDelayedExpansion

rem // Define constants here:
set "_FILE=%~1"         & rem // (use file provided as first command line argument)
set "_FACTOR=%~2"       & rem // (use factor provided as second command line argument)
set "_TAG[1]=Point"     & rem // (name of XML tag containing numeric values)
set "_TAG[2]=Rectangle" & rem // (name of XML tag containing numeric values)
rem "_TAG[...]=..."
set "_ATT[1]=x"         & rem // (name of XML attribute holding a numeric value)
set "_ATT[2]=y"         & rem // (name of XML attribute holding a numeric value)
set "_ATT[3]=width"     & rem // (name of XML attribute holding a numeric value)
set "_ATT[4]=height"    & rem // (name of XML attribute holding a numeric value)
rem "_ATT[...]=..."

要使用此脚本 - 让我们将其称为xml-multiply.bat - ，提供XML文件（result.xml）作为第一个命令行参数，以及将属性值乘以（{{ 1}}加倍他们）作为第二个，像这样：

2

要将输出写入文件（xml-multiply.bat "result.xml" 2 ），请使用：

result_NEW.xml

要替换原始XML文件，请执行以下操作：

xml-multiply.bat "result.xml" 2 > "result_NEW.xml"
