msgid "Hibernate allows you to work with persistent XML data in much the same way you work with persistent POJOs. A parsed XML tree can be thought of as another way of representing the relational data at the object level, instead of POJOs."
msgstr "Hibernate 使得你可以用 XML 数据来进行工作，恰如你用持久化的 POJO 进行工作那样。解析过的 XML 树 可以被认为是代替 POJO 的另外一种在对象层面上表示关系型数据的途径。"

#. Tag: para

msgid "Hibernate supports dom4j as API for manipulating XML trees. You can write queries that retrieve dom4j trees from the database and have any modification you make to the tree automatically synchronized to the database. You can even take an XML document, parse it using dom4j, and write it to the database with any of Hibernate's basic operations: <literal>persist(), saveOrUpdate(), merge(), delete(), replicate() (merging is not yet supported)."
msgstr "Hibernate 支持采用 dom4j 作为操作 XML 树的 API。你可以写一些查询从数据库中检索出 dom4j 树，随后你对这颗树做的任何修改都将自动同步回数据库。你甚至可以用 dom4j 解析 一篇 XML 文档，然后使用 Hibernate 的任一基本操作将它写入数据库：<literal>persist()，saveOrUpdate()，merge()，delete()，replicate() （合并操作merge()目前还不支持）。"

msgid "A single mapping can be used to simultaneously map properties of a class and nodes of an XML document to the database, or, if there is no class to map, it can be used to map just the XML."

msgstr "这个映射使得你既可以把数据作为一棵 dom4j 树那样访问，又可以作为由属性键值对（java <literal>Map）组成的图那样访问。属性名字纯粹是逻辑上的结构，你可以在 HQL 查询中引用它。"

If embed-xml=\"true\", the default, the XML tree for the associated entity (or collection of value type) will be embedded directly in the XML tree for the entity that owns the association. Otherwise, if embed-xml=\"false\", then only the referenced identifier value will appear in the XML for single point associations and collections will not appear at all."
msgstr "对于集合和单值的关联，有一个额外的 <literal>embed-xml 属性可用。这个属性的缺省值是真（embed-xml=\"true\"）。如果 embed-xml=\"true\"，则对应于被关联实体或值类型的集合的XML树将直接嵌入拥有这些关联的实体的 XML 树中。否则，如果 embed-xml=\"false\"，那么对于单值的关联，仅被引用的实体的标识符出现在 XML 树中（被引用实体本身不出现），而集合则根本不出现。"

#. Tag: para
