Answer 1

ID（USE [DATABASE_NAME];），或者更好的是，可重用的类（USE [DATABASE_NAME]; IF DATABASE_PRINCIPAL_ID('role') IS NULL BEGIN -- add user here CREATE ROLE role AUTHORIZATION MyUser; END）适合于为此元素设置样式。

#idname

＆＃13;

.classname

＆＃13;

Answer 2

"//div[@id='siteTable']..."

你也可以试试这个：

arr=(bold_rs_fabio_precuneus_mask.nii.gz mask.nii.gz 
bold_rs_fabio.nii.gz)
