请问如何将<a href="javascript:BlogUtil.download('1694897')" class="file_name">中间1694897这段数字提取出来？

@echo off
for /f "tokens=2 delims='" %%a in ('type aaaaa.txt') do echo %%a
pause>nul

请问、、如果是双引号的话如何解决？？
可以用SED读取特定标签内的内容吗？？

比如说、搜索id="1694899"类似的东西。。我使用CODE
findstr "id=".......""显示出的是其所在行而不是”id="1694899"“
请问如何显示出”id="1694899"“？而不是整行？
