解析XML字符串并构建字符串列表 [英] Parse XML string and build a list of strings

问题描述

我有一个字符串，其内容是XML。我想分隔标签并将其变成Java中的字符串列表。以下是我正在尝试的内容：

I have a string whose content is an XML. I want to separate the tags and make it into a list of string in Java. Below is a something what I am trying:

string xml="<hello><hi a='a' b='b'/><hi a='b' b='a'/></hello>";

我想把它分成如下列表：

I want to separate it into a list like:

list[0]="<hi a='a' b='b'/>"
list[1]="<hi a='b' b='a'/>"

我试图通过JAXB处理器执行此操作，但效果不佳。还尝试了一些使用拆分的愚蠢逻辑，但这也无济于事。有没有其他方法可以达到这个目的？

I tried to do this via JAXB processor but doesn't work well. Also tried some stupid logic using split but that didn't help either. Is there any other way to achieve this?

推荐答案

string xml="<hello><hi a='a' b='b'/><hi a='b' b='a'/></hello>";

//read XML from the given string
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
InputSource is = new InputSource(new StringReader(xml));
Document doc = builder.parse(is);

//this will return a list of xml tags whose name is `hi`
NodeList hiList = document.getElementsByTagName("hi");

//you can iterate over hiList and read/process them
for (int i = 0; i < hiList.getLength(); i++) {
    Node child = hiList.item(i);
    String name = child.getNodeName();
    String contents = child.getTextContent();
}
