通過自己之前轉載的一篇文章，《VS設置增量編譯》，在此基礎上增加了Release版本如何關閉優化并自動生成pdb文件，最終實現思路也比較簡單，就用Python自帶的ElementTree庫讀寫vcxproj文件，廢話不多說，直接上代碼：

import xml

from xml.etree.ElementTree import ElementTree, Element

xml.etree.ElementTree.register_namespace('', 'http://schemas.microsoft.com/developer/msbuild/2003')

def read_xml(in_path):

'''''讀取并解析xml文件

in_path: xml路徑

return: ElementTree'''

tree = ElementTree()

tree.parse(in_path)

return tree

def write_xml(tree, out_path):

'''''將xml文件寫出

tree: xml樹

out_path: 寫出路徑'''

tree.write(out_path, encoding="utf-8", xml_declaration=True)

def if_match(node, kv_map):

'''''判斷某個節點是否包含所有傳入參數屬性

node: 節點

kv_map: 屬性及屬性值組成的map'''

for key in kv_map:

if node.get(key) != kv_map.get(key):

return False

return True

# ----------------search -----------------

def find_nodes(tree, path, namespace=None):

'''''查找某個路徑匹配的所有節點

tree: xml樹

path: 節點路徑'''

return tree.findall(path, namespace)

def get_node_by_keyvalue(nodelist, kv_map):

'''''根據屬性及屬性值定位符合的節點，返回節點

nodelist: 節點列表

kv_map: 匹配屬性及屬性值map'''

result_nodes = []

for node in nodelist:

if if_match(node, kv_map):

result_nodes.append(node)

return result_nodes

# ---------------change ----------------------

def change_node_properties(nodelist, kv_map, is_delete=False):

'''修改/增加 /刪除 節點的屬性及屬性值

nodelist: 節點列表

kv_map:屬性及屬性值map'''

for node in nodelist:

for key in kv_map:

if is_delete:

if key in node.attrib:

del node.attrib[key]

else:

node.set(key, kv_map.get(key))

def change_node_text(nodelist, text, is_add=False, is_delete=False):

'''''改變/增加/刪除一個節點的文本

nodelist:節點列表

text : 更新后的文本'''

for node in nodelist:

if is_add:

node.text += text

elif is_delete:

node.text = ""

else:

node.text = text

def create_node(tag, property_map, content):

'''新造一個節點

tag:節點標簽

property_map:屬性及屬性值map

content: 節點閉合標簽里的文本內容

return 新節點'''

element = Element(tag, property_map)

element.text = content

return element

def add_child_node(nodelist, element):

'''''給一個節點添加子節點

nodelist: 節點列表

element: 子節點'''

for node in nodelist:

node.append(element)

def del_node_by_tagkeyvalue(nodelist, tag, kv_map):

'''''同過屬性及屬性值定位一個節點，并刪除之

nodelist: 父節點列表

tag:子節點標簽

kv_map: 屬性及屬性值列表'''

for parent_node in nodelist:

children = parent_node.getchildren()

for child in children:

if child.tag == tag and if_match(child, kv_map):

parent_node.remove(child)

if __name__ == "__main__":
