我试图在目录中查找文件,其中使用的文件名有时只是完整文件名的一部分。
所以
check_meta=os.listdir(currentPath)
给出
['ANZMeta.xsl','Benefited_Areas','divisons','紧急', 'Error_LOG.txt','hex.dbf','hex.shp','hex.shp_BaseMetadata.xml', 'hex.shx','Maintenance_Areas','Rates.mxd','Regulated_Parking', 'schema.ini','Service_Areas','Local_Govt.lnk的快捷方式','TAB', 'TRC.rar','trc_boundary.dbf','trc_boundary.kml','trc_boundary.prj', 'trc_boundary.sbn','trc_boundary.sbx','trc_boundary.shp', 'trc_boundary.shp.ATGIS29.1772.3444.sr.lock', 'trc_boundary.shp.ATGIS30.2668.2356.sr.lock','trc_boundary.shp.xml', 'trc_boundary.shx','trc_boundary_Metadata.xml.auto', 'trc_boundary_Polygon.dbf','trc_boundary_Polygon.prj', 'trc_boundary_Polygon.sbn','trc_boundary_Polygon.sbx', 'trc_boundary_Polygon.shp', 'trc_boundary_Polygon.shp.ATGIS29.1772.3444.sr.lock', 'trc_boundary_Polygon.shx','trc_boundary_polygon.xml', 'urbanlevy_bdy_region.dbf','Urbanlevy_bdy_region.prj', 'urbanlevy_bdy_region.shp','Urbanlevy_bdy_region.shp.xml', 'urbanlevy_bdy_region.shx','Urbanlevy_bdy_trc.dbf', “Urbanlevy_bdy_trc。 prj','Urbanlevy_bdy_trc.sbn', 'urbanlevy_bdy_trc.sbx','Urbanlevy_bdy_trc.shp', 'urbanlevy_bdy_trc.shp.xml','Urbanlevy_bdy_trc.shx']
我想
existingXML=FileNm[:FileNm.find('.')]
if existingXML+"*"+'.xml' in check_meta: # this is where the issue is
print "exists"
所以有时使用的xml是Urbanlevy_bdy_trc.shp.xml而在其他地方它是Urbanlevy_bdy_trc.xml(无论哪个存在 - 注意不要简单地使用OR函数作为“.shp.xml”,因为有多个文件扩展名比如数据集将具有的tab,ecw等。有时相关的xml文件可能被称为Urbanlevy_bdy_trc_Metadata.shp.xml,所以关键是搜索扩展名为.xml的核心文件名“Urbanlevy_bdy_trc”
我该如何指定? Search and replace multiple lines in xml/text files using python

为什么不直接使用:
searchtext = "sometext"
matching = [ f for f in os.listdir(currentPath) if f.startswith(searchtext) and ".xml" in f]
如果您想检查不同的扩展名,可以将其列出。
exts = (".xml", ".tab", ".shp")
matching = [ f for f in os.listdir(currentPath) if f.startswith(searchtext) and os.path.splitext(f)[-1] in exts]
当然你可以弄清楚正则表达式做同样的事情。
答案 1 :(得分:0)
尝试以下方法:
if any(f.startswith(existingXML) and f.endswith('.xml') for f in check_meta):
print "exists"
any()
内置函数将iterable作为参数,如果任何元素为true,则返回true。我们传递的参数是一个生成器表达式,它将为列表f.startswith(existingXML) and f.endswith('.xml')
中的每个文件f
生成值check_meta
。
正则表达式解决方案可能如下所示:
regex = re.compile(re.escape(existingXML) + '.*\.xml$')
if any(regex.match(f) for f in check_meta):
print "exists"
如果您需要知道哪个条目实际匹配,请使用for循环:
for f in check_meta:
if f.startswith(existingXML) and f.endswith('.xml'):
print "exists, file name:", f
答案 2 :(得分:0)
import fnmatch, posixpath
existingXML = posixpath.splitext(FileNm)[-1]
matchingFiles = fnmatch.filter(check_meta, existingXML + "*" + ".xml")
if not matchingFiles:
raise IOError("no matching XML files")
elif len(matchingFiles) > 1:
print "more than one matching file, using first"
matchingFile = matchingFiles[0]
else: # only one was found, just use it
matchingFile = matchingFiles[0]
