Using wildcard for "if .... in .." statement

Question

I am trying to find files in directories where the file name used is sometimes only a part of the full file name.

So

check_meta=os.listdir(currentPath)

gives

['ANZMeta.xsl', 'Benefited_Areas', 'divisons', 'emergency', 'Error_LOG.txt', 'hex.dbf', 'hex.shp', 'hex.shp_BaseMetadata.xml', 'hex.shx', 'Maintenance_Areas', 'Rates.mxd', 'Regulated_Parking', 'schema.ini', 'Service_Areas', 'Shortcut to Local_Govt.lnk', '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']

I want to

existingXML=FileNm[:FileNm.find('.')]
if  existingXML+"*"+'.xml' in check_meta: # this is where the issue is
   print "exists"

so sometimes the xml to use is Urbanlevy_bdy_trc.shp.xml and at others it is Urbanlevy_bdy_trc.xml (whichever exists -note it is not to simply use a OR function for ".shp.xml" as there are multiple file extentions like tab, ecw etc that the datasets will have). Also sometimes the related xml file maybe called Urbanlevy_bdy_trc_Metadata.shp.xml so the key is just to search for the core file name "Urbanlevy_bdy_trc" with extension .xml

How can I specify this? the purpose of this is mentioned in Search and replace multiple lines in xml/text files using python

Answer 1

why not just use:

searchtext = "sometext"
matching = [ f for f in os.listdir(currentPath) if f.startswith(searchtext) and ".xml" in f]

If you want to check for different extentions you can list them out.

exts = (".xml", ".tab", ".shp")
matching = [ f for f in os.listdir(currentPath) if f.startswith(searchtext) and os.path.splitext(f)[-1] in exts]

Of course you could figure out the regex to do the same thing as well.
