在 mule 中，我有 ac# 类，它是用 XmlSerializer 序列化的（在微软世界中）。xml 序列化类有一个我正在尝试处理的名为 FileContents 的元素（xpath = '/Document/_originalfile/FileContents'）。基本上，这有一个 base64 编码的字符串，它是一个 PDF 文件。我的目标是提取这个“封装”文件并将其作为 PDF 写在本地文件系统上，本地应用程序将处理它并对它做一些事情（比如 OCR 并叠加一个 GUID）并将它放在一个相邻的目录中让另一个骡流传递它。我的问题是从 XML 元素中取出那个该死的字符串。我已经尝试了尽可能多的变压器配方，我认为可以达到 10 次方。我希望有人解释我做错了什么。经过很多头巾之类的，我得到的最接近的是将base64字符串写入PDF文件，该文件实际上只是notepad ++中的文本文件......甚至不接近真正的PDF。然后，它只是 base64 字符串的第一个“块”。例如，在 Altova 中，当我查看元素时，大约有 26 个换行符。它似乎只打破了输出 PDF\text 文件中字符串的第一个块（共 26 个）。我将在这里提供一个基本流程来说明试图做什么，但是，我太激动了，以至于我打破它试图“修复”它，并且从那以后无法重新生成我所做的任何事情。但是，为了方便起见，我已将整个序列化类附加到 c# 应用程序之外。因此，这是我正在使用的 XML 的真实示例，因此被电子笑了。请帮忙！提前致谢！我喜欢骡子，并想专门使用它，因为它很有希望。但是，我对它很陌生，尽管实际上读过一本关于它的书，但我还是失败了。（但是，这本书太棒了，我会推荐给任何接触骡子的人）

这是课程...希望外面的人可以说“哦，简单的家伙...只需将其转换为这个，然后那个，过滤这个，切换那里的set-paylod然后发出砰砰声，你有它输出归档！”

再次，非常感谢骡子用户的不可言喻的智慧！:)

我用这个流程让它更近了一点。至少整个 base64 元素都在输出中，但它被包装在某种 org.dom4j.tree.DefaultText 对象中。我开始担心我必须编写一些 java 代码才能让它工作。:(

核心问题是您.text在 XPath 表达式中缺少获取String它的值，而不是 DOM 节点。请参阅： http: //www.mulesoft.org/documentation/display/current/Mule+Expression+Language+Tips#MuleExpressionLanguageTips-XPathSupport

我不太了解您的第二个流程（为什么是all路由器？为什么所有这些变压器？）所以我将尝试修复您的第一次尝试：

<flow name="XML_Class_to_PDFFlow1">
    <file:inbound-endpoint path="/tmp/mule/in" />
    <mulexml:xml-to-dom-transformer />
    <set-payload
        value="#[xpath('/Document/_originalfile/FileContents/text()').text]" />
    <base64-decoder-transformer />
    <file:outbound-endpoint path="/tmp/mule/out"
        outputPattern="#[message.inboundProperties['originalFilename']]-#[message.id].pdf" />
</flow>
