XMLSlurper appendNode 没有看到变化

我在使用 XMLSlurper 更新 XML 文档时遇到问题。大多数事情都有效，但在某些情况下，“查找”找不到我刚刚附加的节点（appendNode）。新节点在处理结束时就在那里，但当我在添加子节点时找不到。

我发现一篇关于 XMLSlurper 的文章说，找到新的 Node 需要再次调用 parseText 和/或 StreaMarkupBuilder（见下文）。真的吗？！这看起来太笨拙了，我想我应该验证一下。

这是一个代码片段。即使节点刚刚添加，“查找”也会得到 NoChildren 。

    codeNode.appendNode {   
    'lab:vendorData'() {}
}
vendorNode = codeNode.children().find { it.name() == "vendorData" }

“appendNode 不会直接修改 slurped 文档。当使用 StreamingMarkupBuilder 写出文档时，编辑会“即时”应用。” http://markmail.org/message/5nmxbhwna7hr5zcq#query:lated%3A5nmxbhwna7hr5zcq+page:1+mid:bkdesettsnfnieno+state:结果

为什么我找不到我的新节点？！

I am having troubles using XMLSlurper to update an XML document. Most things work, but in some situations a "find" doesn't find a Node I just appended (appendNode). The new Node is there at the end of processing, but is not found when I am in the middle of adding children.

I found a post about XMLSlurper that says that finding the new Node requires calling parseText again and/or StreaMarkupBuilder (see below). Really?! That seems so kludgy that I thought I'd verify on SO.

Here is a code snippet. The "find" gets NoChildren even though the Node was just added.

    codeNode.appendNode {   
    'lab:vendorData'() {}
}
vendorNode = codeNode.children().find { it.name() == "vendorData" }

"appendNode doea not modify the slurped document directly. The edit is applied "on the fly" when the document is written out using StreamingMarkupBuilder."

Why can't I find my new Node?!

这就是我要做的工作。不优雅，但解决了“更新”问题：

    ...
codeNode.appendNode {   
    'lab:vendorData'() {}
}
//-- must re-slurp to see appended node
labDoc = new XmlSlurper().parseText(serializeXml(labDoc))
codeNode = getResultNodeFor( nextResult.getCode() );
vendorNode = codeNode.children().find { it.name() == "vendorData" }
...
def String serializeXml(GPathResult xml){
XmlUtil.serialize(new StreamingMarkupBuilder().bind {
        mkp.declareNamespace("lab", "www.myco.com/LabDocument")
        mkp.yield labDoc
  } )

}

This is what I got to work. Is not elegant, but got past "update" problem:

    ...
codeNode.appendNode {   
    'lab:vendorData'() {}
}
//-- must re-slurp to see appended node
labDoc = new XmlSlurper().parseText(serializeXml(labDoc))
codeNode = getResultNodeFor( nextResult.getCode() );
vendorNode = codeNode.children().find { it.name() == "vendorData" }
...
def String serializeXml(GPathResult xml){
XmlUtil.serialize(new StreamingMarkupBuilder().bind {
        mkp.declareNamespace("lab", "www.myco.com/LabDocument")
        mkp.yield labDoc
  } )

}
