White spaces are required between publicId and systemId

我搜索过,而publicId和systemId似乎与以DOCTYPE开头的XML文件相关.我没有另一个SO posting表示将XSD添加到Eclipse中的XML目录,但这似乎没有什么不同.

一个示例XML如下：

<?xml version="1.0" encoding="UTF-8"?>
 
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
                          http://www.doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
 
    <entity name="Doctrine\Tests\Models\CMS\CmsAddress" table="cms_users">
 
        <named-native-queries>
            <named-native-query name="find-all" result-set-mapping="mapping-find-all">
                <query>SELECT id,country,city FROM cms_addresses</query>
            </named-native-query>
 
            <named-native-query name="find-by-id" result-class="CmsAddress">
                <query>SELECT * FROM cms_addresses WHERE id = ?</query>
            </named-native-query>
 
            <named-native-query name="count" result-set-mapping="mapping-count">
                <query>SELECT COUNT(*) AS count FROM cms_addresses</query>
            </named-native-query>
        </named-native-queries>
 
        <sql-result-set-mappings>
            <sql-result-set-mapping name="mapping-find-all">
                <entity-result entity-class="CmsAddress">
                    <field-result name="id" column="id"/>
                    <field-result name="city" column="city"/>
                    <field-result name="country" column="country"/>
                </entity-result>
            </sql-result-set-mapping>
 
            <sql-result-set-mapping name="mapping-without-fields">
                <entity-result entity-class="CmsAddress"/>
            </sql-result-set-mapping>
 
            <sql-result-set-mapping name="mapping-count">
                <column-result name="count"/>
            </sql-result-set-mapping>
        </sql-result-set-mappings>
 
        <id name="id" type="integer" column="id">
            <generator strategy="AUTO"/>
        </id>
 
        <field name="country" column="country" type="string" length="50"/>
        <field name="city" column="city" type="string" length="50"/>
        <field name="zip" column="zip" type="string" length="50"/>
 
        <one-to-one field="user" target-entity="CmsUser" inversed-by="address">
            <join-column referenced-column-name="id" />
        </one-to-one>
 
    </entity>
</doctrine-mapping>

我有点困惑,接下来要尝试什么.我可以禁用XML验证,但是我讨厌这样做来解决Eclipse中的错误.如果它有任何区别,我使用Eclipse 3.7与PDT.失败的XML文件都是库的一部分,所以我认为它必须是一个Eclipse配置详细信息,必须进行修改/纠正以解决问题,但我不知道什么.

任何建议我可以尝试让我的XML文件验证？
