Answer 1

您可使用标准<代码>java.io的包裹,特别是java.io.FileReader和java.io.BufferedReader。

This will enable you to read the xml file and get the content as standard java.lang.String.

一旦您具备能力,你就能够利用定期表达来过滤其xml型数据。

Answer 2

假设你的XML是有效的、知情的,并且不能把同一名称的标签nes开,你可以使用以下reg子与整个标签相匹配,例如指名的标签<儿童:

<s*child(?:(?!<s*/s*child).)+<s*/s*childs*>

知道在 Java的路里利用这一点,你不得不把所有斜坡翻一番;你想利用<代码”汇编该浮游。模式.DOTALL备选方案。

解释(为了清晰起见删除的选择性白色空间):

<child       # match opening tag
(?:          # then match...
 (?!</child) # as long as it s not at the start of the closing tag:
 .           # any character
)+           # as many times as possible
</child>     # then match the closing tag
