使用STaX解析多个XML片段 [英] Parsing multiple XML fragments with STaX

问题描述

我希望以下内容可以在StAX中解析，

I was hoping the following would be parseable in StAX,

<something a="b"/>
<something a="b"/>

但是当你到达第二个元素时它会窒息。因为没有共同的根元素。 （我不太清楚为什么拉解析器会关心这个特定的问题...无论如何......）

But it chokes when you reach the second element. As there is no common root element. (I'm not too sure why a pull parser cares about this particular issue... anyway...)

我可以伪造一个根元素，例如番石榴：

I can fake a root element, e.g. Guava:

    InputSupplier<Reader> join = CharStreams.join(
            newReaderSupplier("<root>"),
            newReaderSupplier(new File("...")),
            newReaderSupplier("</root>"));

    XMLInputFactory xif = XMLInputFactory.newInstance();
    XMLStreamReader xsr = xif.createXMLStreamReader(join.getInput());
    xsr.nextTag();  // Skip the fake root

所以我的问题只是：有没有办法避免这种黑客行为？一些'片段'模式，我可以将解析器放入？

So my question is just: Is there any way to avoid this hack? Some 'fragment' mode that I can put the parser into?

推荐答案

Woodstox StAX实现显然支持这一点： http://woodstox.codehaus.org/3.2。 9 / javadoc / com / ctc / wstx / api / WstxInputProperties.html＃P_INPUT_PARSING_MODE

The Woodstox StAX implementation does apparently support this: http://woodstox.codehaus.org/3.2.9/javadoc/com/ctc/wstx/api/WstxInputProperties.html#P_INPUT_PARSING_MODE

碰巧我们已经在某些地方使用过Woodstox，但是我没想到谷歌特定于Woodstox的选项！

As it happens we are already using Woodstox in some places, but I didn't think to Google for Woodstox-specific options!
