Openedge 10.2 X文档节点属性顺序

Question

OE 中是否有设置节点属性顺序的方法？

我需要这个结果：

<MyNode MyNode="aaa" Attribute1="bbb" Attribute2="ccc" Attribute3="ddd"/>

我使用这个代码：

hDoc:CREATE-NODE(hAttribute, "MyNode", "ELEMENT").
hAttribute:SET-ATTRIBUTE("MyNode", "aaa").
hAttribute:SET-ATTRIBUTE("Attribute1", "bbb").
hAttribute:SET-ATTRIBUTE("Attribute2", "ccc").
hAttribute:SET-ATTRIBUTE("Attribute3", "ddd").
hNode:APPEND-CHILD(hAttribute).

但它一直在创建这个混乱的输出：

<MyNode Attribute1="bbb" MyNode="aaa" Attribute2="ccc" Attribute3="ddd"/>

还是因为节点名和属性名相同？但是必须有一种方法可以将该节点名称属性放在首位...... 感谢您的帮助！

XML 个属性的顺序无关紧要 (https://www.w3.org/TR/2008/REC-xml-20081126/#sec-starttags)

Note that the order of attribute specifications in a start-tag or empty-element tag is not significant.

使用 DOM 解析器您无法控制顺序 - 请参阅 https://knowledgebase.progress.com/articles/Article/000034225

如果您使用 SAX-WRITER - 因为它是流式传输 - 您可以控制顺序：

def var lcc as longchar no-undo.
def var hsax as handle no-undo.

create sax-writer hsax.
hsax:set-output-destination( "longchar", lcc ).
hsax:formatted = true.
hsax:start-document().
hsax:start-element( "MyNode" ).
hsax:insert-attribute( "MyNode", "aaa" ).
hsax:insert-attribute( "Attribute1", "bbb" ).
hsax:insert-attribute( "Attribute2", "ccc" ).
hsax:insert-attribute( "Attribute3", "ddd" ).
hsax:end-element( "MyNode" ).
hsax:end-document().

message "sax" skip string( lcc ) skip view-as alert-box.
