Python directory operation Python traverses the folder and stores the result as XML

Linux servers have CentOS, fedora, etc., are pre-installed Python, version from 2.4 to 2.5, and the Windows type of server is also most installed Python, so as long as the local computer write a script, upload to the corresponding machine, at run time to modify parameters.

Python operations files and folders use the OS library, and the following code mainly uses several functions:

Os.listdir: List the files and folders under the directory
Os.path.join: Stitching to get the full path of a file/folder
Os.path.isfile: Determine if it is a file
Os.path.splitext: Remove a sub-section from a name

Here is the code for the directory operation

Copy the Code code as follows:

Def search (folder, filter, Allfile):
Folders = Os.listdir (folder)
For name in folders:
Curname = os.path.join (folder, name)
Isfile = Os.path.isfile (curname)
If Isfile:
ext = Os.path.splitext (curname) [1]
Count = Filter.count (EXT)
If count>0:
cur = myfile ()
Cur.name = Curname
Allfile.append (cur)
Else
Search (Curname, filter, Allfile)
Return Allfile

In the return of various information of the file, use the custom class Allfile to save the file information, in the program only use the full path of the file, if you need to record the size of the file, time, type and other information, you can imitate code to expand.
Copy the Code code as follows:

Class MyFile:
def __init__ (self):
Self.name = ""

Once you have an array of stored file information, you can also save it in XML format, the code below, which you need to import from document when you use it xml.dom.minidom

Here is the code saved as XML

Copy the Code code as follows:

def generate (Allfile, XML):
doc = Document ()

Root = doc.createelement ("root")
Doc.appendchild (Root)

For myfile in Allfile:
File = doc.createelement ("file")
Root.appendchild (file)

Name = Doc.createelement ("name")
File.appendchild (name)
Namevalue = Doc.createtextnode (myfile.name)
Name.appendchild (Namevalue)

Print Doc.toprettyxml (indent= "")
F = open (XML, ' A + ')
F.write (Doc.toprettyxml (indent= ""))
F.close ()

The code is executed as follows

Copy the Code code as follows:

if __name__ = = ' __main__ ':
folder = "/usr/local/apache/htdocs"
Filter = [". html", ". htm", ". php"]
Allfile = []
Allfile = Search (folder, filter, Allfile)
Len = Len (allfile)
Print "Found:" + str (len) + "Files"

XML = "Folder.xml"
Generate (Allfile, XML)

In the Linux command line state, execute Python filesearch.py, and you can generate a file named Folder.xml.

If you want to run the program in Windows, you need to change the folder variable to a format under Windows, such as C:\\apache2\htdocs, and then execute C:\python25\python.exe Filesearch.py (This assumes that the Python installation directory is c:\python25)
