问题描述
我有一个带有订单和行数的文档.我需要将订单分解为几行，以便将骆驼分割器设置为xpath，并将订单行作为其值.效果很好.
I have a document with an order and a number of lines. I need to break the order into lines so I have a camel splitter set to xpath with the order line as it's value. This works fine.
但是，我接下来要做的是订单行的元素，这是我想要的，但是在转换它时，我需要来自order元素的信息-但是如果我尝试在拆分后通过xpath获取父元素，这是行不通的.
However, what I get going forward is an element for the order line, which is what I want, but when converting it I need information from the order element - but if I try to get the parent element via xpath following the split, this doesn't work.
Camel是否创建xpath表达式返回的节点的副本，还是返回父文档中的节点列表?如果是前者，我可以做到后者吗?如果是后者，为什么"../*"表达式不返回任何内容?
Does Camel create copies of the nodes returned by the xpath expression, or return a list of nodes within the parent document? If the former, can I make it the latter? If the latter, any ideas why a "../*" expression would return nothing?
谢谢！
磁带.
推荐答案
查看使用Tokenizer时可用的分割选项: http://camel.apache.org/splitter.html
Look at the split options that are available when using a Tokenizer:http://camel.apache.org/splitter.html
您有四种不同的模式(i，w，u，t)，而"w"则保持祖先上下文.在这种情况下，父节点(=您显然需要的东西)将在每个子消息中重复
You have four different modes (i, w, u, t) and the 'w' one is keeping the ancestor context. In such case, the parent node (=the thing you apparently need) will be repeated in each sub-message
默认值:
<m:order><id>123</id><date>2014-02-25</date></m:order>
"w"模式:
<m:orders>
<m:order><id>123</id><date>2014-02-25</date>...</m:order>
</m:orders>
