我有两个类似结构的xmls,结构如下:
<output>
<Erec Spec="1234">
<Property Key="Id">12324</Property>
<Property Key="Price">9000.000000</Property>
<Property Key="Version">5</Property>
<Property Key="Catalog">2</Property>
<Property Key="ColorCode">991</Property>
<Property Key="ColorDesc">Red</Property>
<Property Key="ColorDesc">Blue</Property>
<Property Key="CrossSells">false</Property>
<Property Key="Currency">USD</Property>
</Erec>
...
....
</output>
现在我正在尝试在两个文件中使用xQuery比较,通过一对一的比较,需要查找xml是否保持良好,如果没有找出哪个是缺少的'Key',或者如果值为节点不匹配。
for $old in doc('reference.xml')/output/Erec
for $new in doc('comparison.xml')/output/Erec
return if (data($old/@Spec) = data($new/@Spec))
(:Trying to find if both have same element 'Property' with same attribute value 'Key' but different node value:)
(:How to find if any of the attribute 'Key' is present in $propsOld but missing in $propsNew :)
then for $propsOld in $old/Property
for $propsNew in $new/Property
return if (data($propsOld/@Key) = data($propsNew/@Key))
then if ($propsOld/text() != $propsNew/text() )
then concat("Attribute value mismatch - ",($old/@Spec)," -- ",$propsOld/@Key," -- ",$propsOld/text(),"|", $propsNew/text(),'
' )
else()
else()
else()
这是我能够提出的xQuery,它在节点中找到相同的属性但不同的值。 1)但我无法找到是否缺少某些属性(Key)。 2)有些Erec有像'ColorCode'这样的重复键,它在我现有的输出中也错误地弹出,其匹配的ColorDesc值在一个doc中为Red,在其他文档中为ColorDesc值Blue。我该如何解决这个问题?
这可以用xslt完成吗?

这看起来像是工作......一些改进的建议会有很大的帮助..
for $old in doc('reference.xml')/output/Erec
for $new in doc('comparison.xml')/output/Erec
return if (data($old/@Spec) = data($new/@Spec))
then for $propsOld in $old/Property/@Key
return if(count($new/Property[@Key=$propsOld]) = 0)
then concat(" --- ",$propsOld, " Property doesn't exist ",$new/@Spec,'
' )
else(
if(count($new/Property[@Key=$propsOld]) = 1)
then if($propsOld/../text() != $new/Property[@Key=$propsOld]/text())
then concat("Same Attribute, value mismatch - ",($old/@Spec)," -- ",$propsOld," -- ",$propsOld/../text(),"|", $new/Property[@Key=$propsOld]/text(),'
' )
else()
else()
)
else()
