-# GoWebDAV
-
-[![Build Status](https://travis-ci.org/studio-b12/gowebdav.svg?branch=master)](https://travis-ci.org/studio-b12/gowebdav)
-[![GoDoc](https://godoc.org/github.com/studio-b12/gowebdav?status.svg)](https://godoc.org/github.com/studio-b12/gowebdav)
-[![Go Report Card](https://goreportcard.com/badge/github.com/studio-b12/gowebdav)](https://goreportcard.com/report/github.com/studio-b12/gowebdav)
-
-A golang WebDAV client library.
-
-## Main features
-`gowebdav` library allows to perform following actions on the remote WebDAV server:
-* [create path](#create-path-on-a-webdav-server)
-* [get files list](#get-files-list)
-* [download file](#download-file-to-byte-array)
-* [upload file](#upload-file-from-byte-array)
-* [get information about specified file/folder](#get-information-about-specified-filefolder)
-* [move file to another location](#move-file-to-another-location)
-* [copy file to another location](#copy-file-to-another-location)
-* [delete file](#delete-file)
-
-## Usage
-
-First of all you should create `Client` instance using `NewClient()` function:
-
-```go
-root := "https://webdav.mydomain.me"
-user := "user"
-password := "password"
-
-c := gowebdav.NewClient(root, user, password)
-```
-
-After you can use this `Client` to perform actions, described below.
-
-**NOTICE:** we will not check errors in examples, to focus you on the `gowebdav` library's code, but you should do it in your code!
-
-### Create path on a WebDAV server
-```go
-err := c.Mkdir("folder", 0644)
-```
-In case you want to create several folders you can use `c.MkdirAll()`:
-```go
-err := c.MkdirAll("folder/subfolder/subfolder2", 0644)
-```
-
-### Get files list
-```go
-files, _ := c.ReadDir("folder/subfolder")
-for _, file := range files {
-    //notice that [file] has os.FileInfo type
-    fmt.Println(file.Name())
-}
-```
-
-### Download file to byte array
-```go
-webdavFilePath := "folder/subfolder/file.txt"
-localFilePath := "/tmp/webdav/file.txt"
-
-bytes, _ := c.Read(webdavFilePath)
-ioutil.WriteFile(localFilePath, bytes, 0644)
-```
-
-### Download file via reader
-Also you can use `c.ReadStream()` method:
-```go
-webdavFilePath := "folder/subfolder/file.txt"
-localFilePath := "/tmp/webdav/file.txt"
-
-reader, _ := c.ReadStream(webdavFilePath)
-
-file, _ := os.Create(localFilePath)
-defer file.Close()
-
-io.Copy(file, reader)
-```
-
-### Upload file from byte array
-```go
-webdavFilePath := "folder/subfolder/file.txt"
-localFilePath := "/tmp/webdav/file.txt"
-
-bytes, _ := ioutil.ReadFile(localFilePath)
-
-c.Write(webdavFilePath, bytes, 0644)
-```
-
-### Upload file via writer
-```go
-webdavFilePath := "folder/subfolder/file.txt"
-localFilePath := "/tmp/webdav/file.txt"
-
-file, _ := os.Open(localFilePath)
-defer file.Close()
-
-c.WriteStream(webdavFilePath, file, 0644)
-```
-
-### Get information about specified file/folder
-```go
-webdavFilePath := "folder/subfolder/file.txt"
-
-info := c.Stat(webdavFilePath)
-//notice that [info] has os.FileInfo type
-fmt.Println(info)
-```
-
-### Move file to another location
-```go
-oldPath := "folder/subfolder/file.txt"
-newPath := "folder/subfolder/moved.txt"
-isOverwrite := true
-
-c.Rename(oldPath, newPath, isOverwrite)
-```
-
-### Copy file to another location
-```go
-oldPath := "folder/subfolder/file.txt"
-newPath := "folder/subfolder/file-copy.txt"
-isOverwrite := true
-
-c.Copy(oldPath, newPath, isOverwrite)
-```
-
-### Delete file
-```go
-webdavFilePath := "folder/subfolder/file.txt"
-
-c.Remove(webdavFilePath)
-```

-# Description
-Command line tool for [gowebdav](https://github.com/studio-b12/gowebdav) library.
-
-# Prerequisites
-## Software
-* **OS**: all, which are supported by `Golang`
-* **Golang**: version 1.x
-* **Git**: version 2.14.2 at higher (required to install via `go get`)
-
-# Install
-```sh
-go get -u github.com/studio-b12/gowebdav/cmd/gowebdav
-```
-
-# Usage
-It is recommended to set following environment variables to improve your experience with this tool:
-* `ROOT` is an URL of target WebDAV server (e.g. `https://webdav.mydomain.me/user_root_folder`)
-* `USER` is a login to connect to specified server (e.g. `user`)
-* `PASSWORD` is a password to connect to specified server (e.g. `p@s$w0rD`)
-
-In following examples we suppose that:
-* environment variable `ROOT` is set to `https://webdav.mydomain.me/ufolder`
-* environment variable `USER` is set to `user`
-* environment variable `PASSWORD` is set `p@s$w0rD`
-* folder `/ufolder/temp` exists on the server
-* file `/ufolder/temp/file.txt` exists on the server
-* file `/ufolder/temp/document.rtf` exists on the server
-* file `/tmp/webdav/to_upload.txt` exists on the local machine
-* folder `/tmp/webdav/` is used to download files from the server
-
-## Examples
-
-#### Get content of specified folder
-```sh
-gowebdav -X LS temp
-```
-
-#### Get info about file/folder
-```sh
-gowebdav -X STAT temp
-gowebdav -X STAT temp/file.txt
-```
-
-#### Create folder on the remote server
-```sh
-gowebdav -X MKDIR temp2
-gowebdav -X MKDIRALL all/folders/which-you-want/to_create
-```
-
-#### Download file
-```sh
-gowebdav -X GET temp/document.rtf /tmp/webdav/document.rtf
-```
-
-You may do not specify target local path, in this case file will be downloaded to the current folder with the
-
-#### Upload file
-```sh
-gowebdav -X PUT temp/uploaded.txt /tmp/webdav/to_upload.txt
-```
-
-#### Move file on the remote server
-```sh
-gowebdav -X MV temp/file.txt temp/moved_file.txt
-```
-
-#### Copy file to another location
-```sh
-gowebdav -X MV temp/file.txt temp/file-copy.txt
-```
-
-#### Delete file from the remote server
-```sh
-gowebdav -X DEL temp/file.txt
-```
-
-# Wrapper script
-
-You can create wrapper script for your server (via `$EDITOR ./dav && chmod a+x ./dav`) and add following content to it:
-```sh
-#!/bin/sh
-
-ROOT="https://my.dav.server/" \
-USER="foo" \
-PASSWORD="$(pass dav/foo@my.dav.server)" \
-gowebdav $@
-```
-
-It allows you to use [pass](https://www.passwordstore.org/ "the standard unix password manager") or similar tools to retrieve the password.
-
-## Examples
-
-Using the `dav` wrapper:
-
-```sh
-$ ./dav -X LS /
-
-$ echo hi dav! > hello && ./dav -X PUT /hello
-$ ./dav -X STAT /hello
-$ ./dav -X PUT /hello_dav hello
-$ ./dav -X GET /hello_dav
-$ ./dav -X GET /hello_dav hello.txt
-```

-// Marshal returns the XML encoding of v.

-// Marshal handles an array or slice by marshalling each of the elements.
-// Marshal handles a pointer by marshalling the value it points at or, if the
-// pointer is nil, by writing nothing. Marshal handles an interface value by
-// marshalling the value it contains or, if the interface value is nil, by
-// writing nothing. Marshal handles all other data by writing one or more XML
-// elements containing the data.
-//
-// The name for the XML elements is taken from, in order of preference:
-//     - the tag on the XMLName field, if the data is a struct
-//     - the value of the XMLName field of type xml.Name
-//     - the tag of the struct field used to obtain the data
-//     - the name of the struct field used to obtain the data
-//     - the name of the marshalled type
-//
-// The XML element for a struct contains marshalled elements for each of the
-// exported fields of the struct, with these exceptions:
-//     - the XMLName field, described above, is omitted.
-//     - a field with tag "-" is omitted.
-//     - a field with tag "name,attr" becomes an attribute with
-//       the given name in the XML element.
-//     - a field with tag ",attr" becomes an attribute with the
-//       field name in the XML element.
-//     - a field with tag ",chardata" is written as character data,
-//       not as an XML element.
-//     - a field with tag ",innerxml" is written verbatim, not subject
-//       to the usual marshalling procedure.
-//     - a field with tag ",comment" is written as an XML comment, not
-//       subject to the usual marshalling procedure. It must not contain
-//       the "--" string within it.
-//     - a field with a tag including the "omitempty" option is omitted
-//       if the field value is empty. The empty values are false, 0, any
-//       nil pointer or interface value, and any array, slice, map, or
-//       string of length zero.
-//     - an anonymous struct field is handled as if the fields of its
-//       value were part of the outer struct.
-//
-// If a field uses a tag "a>b>c", then the element c will be nested inside
-// parent elements a and b. Fields that appear next to each other that name

-// BUG(rsc): Mapping between XML elements and data structures is inherently flawed:
-// an XML element is an order-dependent collection of anonymous
-// values, while a data structure is an order-independent collection
-// of named values.
-// See package json for a textual representation more suitable
-// to data structures.
-
-// Unmarshal parses the XML-encoded data and stores the result in
-// the value pointed to by v, which must be an arbitrary struct,
-// slice, or string. Well-formed data that does not fit into v is
-// discarded.
-//
-// Because Unmarshal uses the reflect package, it can only assign
-// to exported (upper case) fields. Unmarshal uses a case-sensitive
-// comparison to match XML element names to tag values and struct
-// field names.
-//
-// Unmarshal maps an XML element to a struct using the following rules.
-// In the rules, the tag of a field refers to the value associated with the
-// key 'xml' in the struct field's tag (see the example above).
-//
-//   * If the struct has a field of type []byte or string with tag
-//      ",innerxml", Unmarshal accumulates the raw XML nested inside the
-//      element in that field. The rest of the rules still apply.
-//
-//   * If the struct has a field named XMLName of type xml.Name,
-//      Unmarshal records the element name in that field.
-//
-//   * If the XMLName field has an associated tag of the form
-//      "name" or "namespace-URL name", the XML element must have
-//      the given name (and, optionally, name space) or else Unmarshal
-//      returns an error.
-//
-//   * If the XML element has an attribute whose name matches a
-//      struct field name with an associated tag containing ",attr" or
-//      the explicit name in a struct field tag of the form "name,attr",
-//      Unmarshal records the attribute value in that field.
-//
-//   * If the XML element contains character data, that data is
-//      accumulated in the first struct field that has tag ",chardata".
-//      The struct field may have type []byte or string.
-//      If there is no such field, the character data is discarded.
-//
-//   * If the XML element contains comments, they are accumulated in
-//      the first struct field that has tag ",comment".  The struct
-//      field may have type []byte or string. If there is no such
-//      field, the comments are discarded.
-//
-//   * If the XML element contains a sub-element whose name matches
-//      the prefix of a tag formatted as "a" or "a>b>c", unmarshal
-//      will descend into the XML structure looking for elements with the
-//      given names, and will map the innermost elements to that struct
-//      field. A tag starting with ">" is equivalent to one starting
-//      with the field name followed by ">".
-//
-//   * If the XML element contains a sub-element whose name matches
-//      a struct field's XMLName tag and the struct field has no
-//      explicit name tag as per the previous rule, unmarshal maps
-//      the sub-element to that struct field.
-//
-//   * If the XML element contains a sub-element whose name matches a
-//      field without any mode flags (",attr", ",chardata", etc), Unmarshal
-//      maps the sub-element to that struct field.
-//
-//   * If the XML element contains a sub-element that hasn't matched any
-//      of the above rules and the struct has a field with tag ",any",
-//      unmarshal maps the sub-element to that struct field.
-//
-//   * An anonymous struct field is handled as if the fields of its
-//      value were part of the outer struct.
-//
-//   * A struct field with tag "-" is never unmarshalled into.
-//
-// Unmarshal maps an XML element to a string or []byte by saving the
-// concatenation of that element's character data in the string or
-// []byte. The saved []byte is never nil.
-//
-// Unmarshal maps an attribute value to a string or []byte by saving
-// the value in the string or slice.
-//
-// Unmarshal maps an XML element to a slice by extending the length of
-// the slice and mapping the element to the newly created value.
-//
-// Unmarshal maps an XML element or attribute value to a bool by
-// setting it to the boolean value represented by the string.
