合并 XML 文档 [英] Merge XML documents

问题描述

我需要合并"两个 XML 文档，覆盖重叠的属性和元素.例如，如果我有 document1:

I need to "merge" two XML documents, overwriting the overlapsed attributes and elements. For instance if I have document1:

<mapping>
    <key value="assigned">
        <a/>
    </key>
    <whatever attribute="x">
        <k/>
        <j/>
    </whatever>
</mapping>

和document2:

<mapping>
    <key value="identity">
        <a/>
        <b/>
    </key>
</mapping>

我想像这样合并两者:

<mapping>
    <key value="identity">
        <a/>
        <b/>
    </key>
    <whatever attribute="x">
        <k/>
        <j/>
    </whatever>
</mapping>

我更喜欢基于 Java 或 XSLT 的解决方案，ant 会很好，但如果在 中有一种简单的方法可以做到这一点>Rake、Ruby 或 Python 请不要害羞:-)

I prefer Java or XSLT-based solutions, ant will do fine, but if there's an easy way to do that in Rake, Ruby or Python please don't be shy :-)

实际上我发现我更愿意使用自动化工具/脚本，甚至 自己编写，因为手动合并大约 30 个 XML 文件有点笨拙...... :-(

actually I find I'd rather use an automated tool/script, even writing it by myself, because manually merging some 30 XML files is a bit unwieldy... :-(

推荐答案

如果您喜欢 XSLT，这里有一个我以前用过的不错的合并脚本:Oliver 的 XSLT 页面

If you like XSLT, there's a nice merge script I've used before at: Oliver's XSLT page
