Parse Path (ModelBuilder)

Summary

Parses an input into its file name, extension, path, and the last workspace name. The output can be used as an inline variable in the output name of other tools.

Learn how Parse Path works in ModelBuilder

Usage

• This tool is intended for use in ModelBuilder, not in Python scripting.

• More than one variable name can be added to create unique names for the output, for example, C:\Temp\Out_%Name%_%Workspace Name%.

• If the input to the Parse Path tool is C:\1Tool Data\City Roads.shp, it is parsed into the following outputs:

  Parse	Result
  Path	C:\1Tool Data
  Name	City Roads
  Extension	shp
  Workspace Name	1Tool Data

  If the Format Name, Extension and Workspace parameter is checked, the path above will be parsed into the following outputs:

  Parse	Result
  Path	C:\1Tool Data
  Name	City_Roads
  Extension	shp
  Workspace Name	_1Tool_Data

• The same functionality can be accessed in scripting with the Python os module. For example, if you pass an input variable:

  inData = r"C:\1Tool Data\City Roads.shp", then

  • To get the name City Roads
    import os
    name = os.path.basename(inData)

  • To get the path C:\1Tool Data
    import os
    path = os.path.dirname(inData)

  • To get the file extension shp
    import os
    ext = os.path.splitext(inData)[1][1:]

  • To get the workspace name 1Tool Data
    import os
    folder = os.path.basename(os.path.dirname(inData))

  To parse paths in a similar way to when the Format Name, Extension and Workspace parameter is checked:

  • To get the name City_Roads
    import os
    import re
    name = os.path.basename(inData)
    name = re.sub('[^0-9a-zA-Z]+', '_', name)
    if name[0].isdigit():
        name = "_" + name

  • To get the path C:\1Tool Data
    import os
    path = os.path.dirname(inData)

  • To get the file extension shp
    import os
    ext = os.path.splitext(inData)[1][1:]

  • To get the workspace name _1Tool_Data
    import os
    import re
    folder = os.path.basename(os.path.dirname(inData))
    folder = re.sub('[^0-9a-zA-Z]+', '_', folder)
    if folder[0].isdigit():
        folder = "_" + folder

• The Path output of Parse Path has a workspace data type and can be connected directly as an input to the Create Feature Class tool's Feature Class Location parameter, which accepts a workspace data type as input. For tools such as Copy that do not have a workspace data type parameter, the Path value can be passed to the tool using inline variable substitution such as %Path%\Out_%Name%.%Extension%.

  

Syntax

arcpy.mb.ParsePathExt(in_data_element, {format})

Parameter	Explanation	Data Type
in_data_element	The input values to parse.	Any Value
format (Optional)	Removes all reserved characters. Given the input value of C:\1Tool Data\InputFC.shp: Path—The output will be the file path, for example, C:\1Tool Data. Name—The output will be the file name, for example, InputFC. Extension—The output will be the file extension, for example, shp. Workspace Name—The output will be the workspace name, for example, _1Tool_Data.	Boolean

Derived Output

Name	Explanation	Data Type
path	The workspace of the input.	Workspace
name	The file name, excluding the extension.	String
extension_type	The file extension.	String
workspace_name	The name of the workspace.	String

Environments

This tool does not use any geoprocessing environments.
