我正在尝试将atom-pub CMIS 1.0绑定加载到EXTJS中,标记中的冒号正在阻止XML读取器执行其工作。例如,xml看起来像:
<atom:entry xmlns:atom="http://www.w3.org/2005/Atom" xmlns:cmis="http://docs.oasis- open.org/ns/cmis/core/200908/" xmlns:cmisra="http://docs.oasis-open.org/ns/cmis/restatom/200908/" xmlns:app="http://www.w3.org/2007/app">

<atom:updated>2013-11-28T00:01:22Z</atom:updated>
<cmisra:object xmlns:ns3="http://docs.oasis-open.org/ns/cmis/messaging/200908/">
<cmis:properties>
<cmis:propertyId queryName="cmis:allowedChildObjectTypeIds" displayName="Allowed Child Types" localName="cmis:allowedChildObjectTypeIds" propertyDefinitionId="cmis:allowedChildObjectTypeIds">
<cmis:value>*</cmis:value>
</cmis:propertyId>
<cmis:propertyId queryName="cmis:objectTypeId" displayName="Type-Id" localName="cmis:objectTypeId" propertyDefinitionId="cmis:objectTypeId">
<cmis:value>cmis:folder</cmis:value>
</cmis:propertyId>
<cmis:propertyString queryName="cmis:path" displayName="Path" localName="cmis:path" propertyDefinitionId="cmis:path">
<cmis:value>/Root/396271/Folder1</cmis:value>
</cmis:propertyString>
<cmis:propertyString queryName="cmis:name" displayName="Name" localName="cmis:name" propertyDefinitionId="cmis:name">
<cmis:value>Folder1</cmis:value>
</cmis:propertyString>
..... etc.
例如,如果我考虑一个简单的例子
<?xml version="1.0" encoding="UTF-8"?>
<users>
<user attr="test ed">
<id:number>1</id:number>
<name>Ed Spencer</name>
<email>ed@sencha.com</email>
</user>
<user attr="test abe">
<id:number>2</id:number>
<name>Abe Elias</name>
<email>abe@sencha.com</email>
</user>
</users>
我使用EXTJS代码
Ext.onReady(function () {
Ext.define('User', {
extend: 'Ext.data.Model',
autoload: true,
fields: [{ name: "id", mapping: 'id:number'},
{ name: "name", mapping: 'name'},
{ name: "email", mapping: 'email'},
{ name: "attr", mapping: '@attr'}]
});
var store = Ext.create('Ext.data.Store', {
model: 'User',
proxy: {
type: 'ajax',
url : 'users.xml',
reader: {
type: 'xml',
record: 'user',
root: 'users'
}
}
});
store.load();
});
我应该为id或备用代码的映射做些什么?
fields: [{ name: "id", mapping: 'id:number'} ????? escape the ':' some how?
如果可能的话,我会尽量避免编写大量自定义XML解析代码,并依赖EXTJS阅读器,而CMIS 1.1浏览器绑定不适用于我的ECM。
我发现解决方案在EXTJS 4中得到了解决,但在我熟悉的早期版本中没有(3.4):名称空间字符|是在EXTJS 4DomQuery 中引入的
因此,如果示例XML有一个定义的名称空间,例如xmlns:id="http://my.example.com/id
那么名称空间从以前修改的XML是:
<?xml version="1.0" encoding="UTF-8"?>
<users xmlns:id="http://my.example.com/id">
<id:user attr="test ed">
<id:id>1</id:id>
<id:name>
<id:first attr2="test ed 2">Ed</id:first>
<id:last>Spencer</id:last>
</id:name>
<id:email>ed@sencha.com</id:email>
</id:user>
<id:user attr="test abe">
<id:id>2</id:id>
<id:name>
<id:first attr2="test ed 2">Abe</id:first>
<id:last>Elias</id:last>
</id:name>
<id:email>abe@sencha.com</id:email>
</id:user>
</users>
这样,下面的EXTJS代码将在fields: [{ name: "id", mapping: 'id|id'}
中工作
这就是的完整解决方案

var test;
Ext.onReady(function () {

var store = Ext.create('Ext.data.Store', {

proxy: {
type: 'ajax',

<body>
<h1>EXTJS Example</h1>
<p id="demo">Here we try to load XML into an EXTJS XML Reader</p>
<button type="button" onclick="getResult();">getResult</button>
</body>
</html>
还要注意,如果在定义名称空间之前在根元素中使用了名称空间,那么XML读取器中的根定义需要使用:而不是|字符,即root: 'id:users'
我也面临着与使用extjs-4.2.1 相同的问题
我的示例xml
<RDF>
<Seq about="urn:productManagement:root" type="ROOT" ac:maxLevels="25">
<li>
<Description ac:name="name1" ac:type="type1"/>
</li>
</Seq>
</RDF>
上述xml 的模型
Ext.define('TR.model.TreeControlModel', {
extend: 'Ext.data.Model',
fields: [
{ name: 'about', mapping:'@about'},
{ name: 'type', mapping:'li>Description@ac:type'},
{ name: "name", mapping:'li>Description@ac:name'}
]
});
我尝试用|替换管道,但对我不起作用。需要帮助。
