开发中使用微软UI自动化框架FlaUI，在抓取chrome网页元素时，无法抓取到网页内元素，经查资料发现是chrome启动方式不对，具体原因如下：
Chrome page content can be seen by UIA if you run chrome --force-renderer-accessibility. Only for existing Chrome process it won't work. Though user can create a new tab chrome://accessibility manually and enable UIA for all or some chosen pages. This method also works for AT-SPI accessibility technology on Linux. Of course, Selenium WebDriver is an industry standard here. But another way exists. Both Mozilla and IE support UIA by default.
设置chrome以“--force-renderer-accessibility”启动，或者在chrome://accessibility页中选中UIA。（ps：国内关于FlaUI的资料是在是太少了）
