使用XML内容哪种语言最简单,最快速?

如何解决《使用XML内容哪种语言最简单,最快速?》经验,为你挑选了3个好方法。

我们的开发人员拥有这些语言的知识 - Ruby,Python,.Net或Java.我们正在开发一个主要处理XML文档的应用程序.大部分工作是将预定义的XML文件转换为数据库表,通过数据库提供XML文档之间的映射,从数据库创建报告等.哪种语言最简单,最快速?(这是一个网络应用程序)



1> S.Lott..:

动态语言规则.为什么?映射很容易编码和更改.您不必重新编译和重建.

实际上,通过一点点聪明,您可以将"XML XPATH转换为标记 - >数据库表字段"映射为主应用程序导入的不相交的Python代码块.

Python代码块您的配置文件.它不是描述配置的.ini文件或.properties文件.这配置.

我们使用Python,xml.etree和SQLAlchemy(将SQL从程序中分离出来),因为我们只需很少的工作量和灵活性即可运行.


source.py

"""A particular XML parser.  Formats change, so sometimes this changes, too."""

import xml.etree.ElementTree as xml

class SSXML_Source( object ):
    ns0= "urn:schemas-microsoft-com:office:spreadsheet"
    ns1= "urn:schemas-microsoft-com:office:excel"
    def __init__( self, aFileName, *sheets ):
        """Initialize a XML source.
        XXX - Create better sheet filtering here, in the constructor.
        @param aFileName: the file name.
        """
        super( SSXML_Source, self ).__init__( aFileName )
        self.log= logging.getLogger( "source.PCIX_XLS" )
        self.dom= etree.parse( aFileName ).getroot()
    def sheets( self ):
        for wb in self.dom.getiterator("{%s}Workbook" % ( self.ns0, ) ):
            for ws in wb.getiterator( "{%s}Worksheet" % ( self.ns0, ) ):
                yield ws
    def rows( self ):
        for s in self.sheets():
            print s.attrib["{%s}Name" % ( self.ns0, ) ]
            for t in s.getiterator( "{%s}Table" % ( self.ns0, ) ):
                for r in t.getiterator( "{%s}Row" % ( self.ns0, ) ):
                    # The XML may not be really useful.
                    # In some cases, you may have to convert to something useful
                    yield r

model.py

"""This is your target object.  
It's part of the problem domain; it rarely changes.
"""
class MyTargetObject( object ):
    def __init__( self ):
        self.someAttr= ""
        self.anotherAttr= ""
        self.this= 0
        self.that= 3.14159
    def aMethod( self ):
        """etc."""
        pass

builder_today.py许多映射配置之一

"""One of many builders.  This changes all the time to fit
specific needs and situations.  The goal is to keep this
short and to-the-point so that it has the mapping and nothing
but the mapping.
"""

import model

class MyTargetBuilder( object ):
    def makeFromXML( self, element ):
        result= model.MyTargetObject()
        result.someAttr= element.findtext( "Some" )
        result.anotherAttr= element.findtext( "Another" )
        result.this= int( element.findtext( "This" ) )
        result.that= float( element.findtext( "that" ) )
        return result

loader.py

"""An application that maps from XML to the domain object
using a configurable "builder".
"""
import model
import source
import builder_1
import builder_2
import builder_today

# Configure this:  pick a builder is appropriate for the data:
b= builder_today.MyTargetBuilder()

s= source.SSXML_Source( sys.argv[1] )
for r in s.rows():
    data= b.makeFromXML( r )
    # ... persist data with a DB save or file write

要进行更改,您可以更正构建器或创建新构建器.您可以调整加载程序源以标识将使用的构建器.您可以毫不费力地选择构建器作为命令行参数.动态语言中的动态导入对我来说似乎有些过分,但它们很方便.



2> AJ...:

XSLT

我建议使用XSLT模板根据需要将XML转换为INSERT语句(或任何你需要的).
您应该可以从您提到的任何语言调用XSLT.

与长期合作相比,这将导致更少的代码.



3> Chris Fulsto..:

在.NET中,C#3.0和VB9为使用LINQ to XML处理XML提供了出色的支持:
