进入txt文件,由％tab％delimiter分隔？
应该有3或4列：
1)来自示例数据的文件夹描述：<文件夹描述=“浏览器 - Windows”>
2)来自示例数据的浏览器类型：< folder description =“Legacy Browsers”>
3)来自示例数据的用户代理：< useragent description =“Avant Browser 1.2”useragent =“Avant Browser / 1.2.789rel1(http://www.avantbrowser.com)”app 在这里,我看到第一个问题,因为某些浏览器不在文件夹< folder description =“Legacy Browsers”>“但在< separator />下
所以第一列应该定义系统,第二列是类型,第三列是浏览器.

这解析了该行的一个标记,我现在将使用它.
但我相信下面的代码就是你要找的.
因为文件夹的数量不同,我交换了输出中列的顺序.我首先放置浏览器描述,然后是文件夹,每列一个.这允许修复每列的定义.
我用jeb的答案中的信息包括“作为FOR分隔符.
编辑 – 我简化了代码
注 – 首次尝试使用的是使用Internet Explorer检索的XML副本.我发现IE改变了文件的格式.此代码高度依赖于文件的确切格式,因此它不适用于原始XML.它还可以作为解析为什么批处理是解析XML的不良选择的一个例子
@echo off
setlocal enableDelayedExpansion
::Define the files to use - change as needed
set input="test.xml"
set output="result.txt"
::The assignment below should have exactly one TAB character between = and "
set "TAB= "
set cnt=0
set "folder0="
>%output% (
for /f usebackq^ tokens^=1^,2^ delims^=^=^" %%A in (%input%) do (
for %%N in (!cnt!) do (
if "%%A"=="- <folder description" (
set /a cnt+=1
for %%M in (!cnt!) do set "folder%%M=!folder%%N!%TAB%%%B"
)
if "%%A"==" </folder>" (
set /a cnt-=1
)
if "%%A"==" <useragent description" (
echo %%B!folder%%N!
)
)
)
)
如果代码将失败！出现在任何描述中,因为延迟扩展会破坏包含！的任何FOR变量的扩展.我查了一下,你的文件不包含！在任何描述中.
可以修改代码来处理！在描述中,但它会变得更复杂.它需要打开和关闭延迟扩展,并在ENDLOCAL屏障上保留变量值.
上面的代码高度依赖于XML的格式.如果删除非标准破折号,或者空格排列发生变化,则会失败.
以下变体更加健壮,但仍需要每行包含一个XML标记.
@echo off
setlocal enableDelayedExpansion
::Define the files to use - change as needed
set input="test.xml"
set output="result.txt"
::The assignment below should have exactly one TAB character between = and "
set "TAB= "
set cnt=0
set "folder0="
>%output% (
for /f usebackq^ tokens^=1^,2^ delims^=^=^" %%A in (%input%) do (
for %%N in (!cnt!) do (
set "test=%%A"
if "!test:<folder description=!" neq "!test!" (
set /a cnt+=1
for %%M in (!cnt!) do set "folder%%M=!folder%%N!%TAB%%%B"
)
if "!test:</folder>=!" neq "!test!" (
set /a cnt-=1
)
if "!test:<useragent description=!" neq "!test!" (
echo %%B!folder%%N!
)
)
)
)
编辑 – 最后一个版本
这是一个可以处理的版本！在数据中.我在输出中添加了一个额外的列.第一列仍然是浏览器描述.第二列是useragent字符串.其余列是文件夹.该解决方案使用延迟扩展切换技术.它还使用额外的FOR / F来保留ENDLOCAL屏障的变量值.
