Question

我收到以下xml响应，我需要解析，以便我得到的是URL128 xml元素值的集合。有关在Java中实现这一目标的最有效方法的任何想法吗？

  <?xml version="1.0" encoding="utf-8"?>
    <imagesXML>
        <Images>
            <Image>
                <ImageUID Scope="Public" Type="Guid" Value="{7f2535d0-9a41-4997-9694-0a4de569e6d9}"/>
                <CorbisID Scope="Public" Type="String" Value="42-15534232"/>
                <Title Scope="Public" Type="String" Value="Animal"/>
                <CreditLine Scope="Public" Type="String" Value="¬© Robert Llewellyn/Corbis"/>
                <IsRoyaltyFree Scope="Public" Type="Boolean" Value="False"/><AspectRatio Scope="Public" Type="String" Value="1.500000"/>
                <URL128 Scope="Public" Type="String" Value="http://cachens.corbis.com/CorbisImage/thumb/15/53/42/15534232/42-15534232.jpg"/>
            </Image>
            <Image>
                <ImageUID Scope="Public" Type="Guid" Value="{7f2535d0-9a41-4997-9694-0a4de569e6d9}"/>
                <CorbisID Scope="Public" Type="String" Value="42-15534232"/>
                <Title Scope="Public" Type="String" Value="Animal"/>
                <CreditLine Scope="Public" Type="String" Value="¬© Robert Llewellyn/Corbis"/>
                <IsRoyaltyFree Scope="Public" Type="Boolean" Value="False"/><AspectRatio Scope="Public" Type="String" Value="1.500000"/>
                <URL128 Scope="Public" Type="String" Value="http://cachens.corbis.com/CorbisImage/thumb/15/53/42/15534232/42-15534232.jpg"/>
            </Image>
        </Images>
    </imagesXML>

Answer 1

Java XPath API易于使用：

String xmlData = "<test><one><URL128 myAttribute='value' /></one></test>";
InputSource source = new InputSource(new StringReader(xmlData)); //or use your own input source

XPath xPath = XPathFactory.newInstance().newXPath();

NodeList list = (NodeList)xPath.evaluate("//URL128", source, XPathConstants.NODESET);
List<Element> elements = new ArrayList<Element>(list.getLength());
for (int i = 0; i < list.getLength(); i++)
{
    elements.add((Element)list.item(i));
}

Answer 2

使用SAX并实施startElement方法，以便在元素名称为“URL128”的情况下，提取三个属性Scope，Type和{{1将它们存储在自定义对象中，并将此对象添加到Value。

既简单又快捷。

使用Java为特定元素解析XML
