摘要： In one embodiment, a method of parsing an XML data stream comprises receiving an XML data stream containing a namespace prefix and an associated element tag name. The element tag name is associated with an element tag. The namespace prefix and the element tag name are converted into a token that uniquely represents a namespace specification that is associated with the namespace prefix and the element tag. A stack is defined and is configured to receive one or more tokens during parsing of the XML data stream. Parsing of the XML data stream is performed without requiring an XML tree structure comprising an XML document embodied by the XML data stream, to be built.

摘要： Various features enable an XML data stream to be parsed without the need to build a hierarchical tree structure for the XML document. In the described embodiment, the concept of an element or namespace stack is utilized as a way of organizing parsing activities and maintaining a definable place within the structure of the XML document. Various structures work together with the element or namespace stack to facilitate piecewise parsing of the XML data stream. One structure is a namespace hierarchy that is a collection of namespace objects that each represent a namespace specification that is encountered in the XML data stream. Each object includes a namespace prefix and an associated namespace specification. This structure creates a hierarchical organization that is used for mapping a particular encountered namespace specification into a unique value that represents both the namespace specification and an element tag in which the namespace specification occurs. Another structure is a dictionary collection that contains one or more dictionaries. Each dictionary is specifically associated with a namespace specification that is encountered in the XML data stream. The dictionaries contain entries for one or more tag names and each name's associated unique token. The token is returned and placed on the element stack along with another special value that enables the proper state to be maintained during processing of the XML data stream. The stack also includes a text accumulation buffer that can hold any text that is contained within an element (between the element tags). When an XML element is encountered, the element stack is used to organize parsing activities as the parser makes its way through the XML data stream.
摘要翻译：各种功能使得可以解析XML数据流，而无需为XML文档构建分层树结构。在所描述的实施例中，元素或命名空间堆栈的概念被用作组织解析活动并在XML文档的结构内维护可定义的位置的方式。各种结构与元素或命名空间堆栈一起工作，以便于对XML数据流进行分段解析。一个结构是命名空间层次结构，它是命名空间对象的集合，每个对象都表示在XML数据流中遇到的命名空间规范。每个对象包括命名空间前缀和关联的命名空间规范。此结构创建一个分层组织，用于将特定遇到的命名空间规范映射到表示命名空间规范发生的命名空间规范和元素标记的唯一值。另一个结构是包含一个或多个字典的字典集合。每个字典与XML数据流中遇到的命名空间规范特别相关。字典包含一个或多个标签名称和每个名称相关的唯一标记的条目。令牌被返回并放置在元素堆栈上，以及另外一个特殊的值，可以在处理XML数据流期间保持正确的状态。堆栈还包括一个文本累积缓冲区，可以容纳元素中包含的任何文本（元素标签之间）。当遇到XML元素时，元素堆栈用于组织解析活动，因为解析器通过XML数据流。

摘要： Metadata may be stored in, and retrieved from, a scalable, fault-tolerant metadata service. In one example, metadata is divided into partitions, and each partition is served by one or more nodes. For each partition, a first one of the nodes may handle read and write requests, and the other nodes may handle read requests in the event that the first node is down or is experiencing high load. When a request is made with respect to metadata, a metadata server may identify a node, in the partition to which the metadata is assigned, to which the request is to be made. The entity that is making the request then contacts that node, and requests the read or write on the metadata. In a partition, metadata may be replicated between the first node and the other nodes using a log-based replication protocol.

摘要： Systems for parsing an XML data stream are described. In one embodiment, the system is configured to receive an XML data stream comprising one or more element tags and determine whether an element tag contains a namespace declaration. The system creates one or more namespace objects if an element tag contains one or more respective namespace declarations, each namespace object corresponding to one namespace declaration. The system associates namespace objects with one another if more than one namespace object is created and associates each namespace object with a dictionary that contains one or more entries that are associated with an element tag.

摘要： An architecture for processing an Extensible Markup Language (XML) document converts schema elements in the XML document to data type definition (DTD) objects that can be used to validate data elements in the XML document. The architecture utilizes a node factory design in which an XML parser calls one or more node factory interfaces to construct an in-memory tree representation of an XML document. One of the node factory interfaces is a schema node factory, which is a thin layer that receives calls from the parser to build nodes in the tree representation and translates those calls to calls to a schema builder. The schema builder is a table driven interface that converts the schema elements in the XML document into DTD objects. The DTD objects are then used to validate the data elements as belonging to the schema. If valid, the data elements are used to construct the tree representation.
摘要翻译：用于处理可扩展标记语言（XML）文档的架构将XML文档中的模式元素转换为可用于验证XML文档中的数据元素的数据类型定义（DTD）对象。该架构使用节点工厂设计，其中XML解析器调用一个或多个节点工厂接口来构造XML文档的内存中的树表示。节点工厂接口之一是一个模式节点工厂，它是从分析器接收调用以构建树表示中的节点的薄层，并将这些调用转换为对构建器的调用。模式构建器是一个表驱动接口，将XML文档中的模式元素转换为DTD对象。然后，DTD对象用于验证属于模式的数据元素。如果有效，则使用数据元素构建树表示。
