The XMLEXISTS is a Boolean function that takes an XPath expression as input and returns FALSE if the XPath expression returns an empty sequence and TRUE otherwise.
XMLEXISTS是一个Boolean函数，它接受一个XPath表达式作为输入；如果这个XPath表达式返回空序列，它会返回FALSE，否则返回TRUE。
Technically speaking, a regular expression is a string (that is, a sequence of characters composed of letters, Numbers, and symbols) that represents a pattern defining zero or more strings.
从技术角度而言，正则表达式是表示某种模式的字符串(也就是说，由字母、数字和符号组成的字符序列)，用于定义零或更长的字符串。
XPath provides primitives for moving around the XML tree, for selecting nodes according to name or by the use of a Boolean expression, and for applying functions to a sequence of nodes.
XPath支持在XML树中移动、根据节点名称或通过使用Boolean表达式选择节点以及对一系列节点应用函数。
Regular expressions: search word (s) will be regarded as a regular expression (in keyword search words will be treated as a sequence of regular expressions).
正则表达式：搜索单词将作为一个正则表达式(在关键字搜索中，单词被视为正则表达式系列)。
