xmllint其实是由一个叫libxml2的c语言库函数实现的一个小工具,因此效率比较高,对不同系统的支持度也很好,功能也比较全。他一般属于libxml2-utils这个软件包,因此类似与sudo 的命令就可以安装。


APT YUM(Ubuntu/Debian )

apt install -y libxml2-utils
yum install -y libxml2-utils


brew install xmlstarlet

# 从标准输出管道传递
cat settings.xml | xmllint --foramt - 

# 从标准输入管道传递
xmllint --html --xpath '/html/body/h1[1]' - <<EOF


# 压缩输出
xmllint --noblanks settings.xml > settings-noblank.xml

# 格式化输出
xmllint --format settings.xml > settings-format.xml


xmllint --schema settings-1.0.0.xsd settings.xml

# xsd文件可以在XML的命名空间中找到下载链接
# 语法校验成功后会输出"validates",不成功会输出"fails to validate"
# 如果要求只输出校验结果不显示XML内容,可加--noout参数
