arcgis10.0及以上版本，使用arcpy加载在arctoolbox中实现对所有mxd中特定图层的定义查询_arcpy mxd选择图层

代码：

#coding:gbk
#author:yangyong
#会报错，不过不影响正常使用
#cunMing表示村落名称，可用于定义查询，注意用%
import arcpy,os,re
import arcpy.mapping as mapping
global cunMing
 
import sys
reload(sys)
sys.setdefaultencoding("utf-8")
 
inputMxdPath = arcpy.GetParameterAsText(0)	#floder  eg:O:\arcgis_directory\MXD\RHYXT
outputMxdPath = arcpy.GetParameterAsText(1)	#floader  eg:eg:O:\arcgis_directory\MXD\RHYXT\print
lyrName = arcpy.GetParameterAsText(2)		#string  eg: XZQ
sqlSentence = arcpy.GetParameter(3)	#string eg: [XZQMC] = "%(cunMing)s"    （cunMing 会自动替换为具体的村名)
 
 
 
for root,dirs,names in os.walk(r"%s"%inputMxdPath):
	for name in names:
		if name[-4:].lower() == ".mxd":
			a = str('%s')%name
			if u"镇" in name:

			elif "街道" in name:
				b = re.split(u"街道", a)[1]
				c = re.split(u"村", b)[0]
				cunMing = c + "村"
			arcpy.AddMessage("%s"%cunMing + "has be Recognition")
			mxd = mapping.MapDocument(r"%s"%os.path.join(root,name))
			df  = mapping.ListDataFrames(mxd,"")[0]
			lyrs = arcpy.mapping.ListLayers(mxd,"",df)
			for lyr in lyrs:

					lyr.definitionQuery = whereClause
					newName = os.path.join(outputMxdPath,name)

					del name,b,c
					mxd.saveACopy(r"%s"%newName)
