通过自己之前转载的一篇文章，《VS设置增量编译》，在此基础上增加了Release版本如何关闭优化并自动生成pdb文件，最终实现思路也比较简单，就用Python自带的ElementTree库读写vcxproj文件，废话不多说，直接上代码：

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):

'''''读取并解析xml文件

in_path: xml路径

return: ElementTree'''

tree = ElementTree()

tree.parse(in_path)

return tree

def write_xml(tree, out_path):

'''''将xml文件写出

tree: xml树

out_path: 写出路径'''

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

def if_match(node, kv_map):

'''''判断某个节点是否包含所有传入参数属性

node: 节点

kv_map: 属性及属性值组成的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):

'''''查找某个路径匹配的所有节点

tree: xml树

path: 节点路径'''

return tree.findall(path, namespace)

def get_node_by_keyvalue(nodelist, kv_map):

'''''根据属性及属性值定位符合的节点，返回节点

nodelist: 节点列表

kv_map: 匹配属性及属性值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 /删除 节点的属性及属性值

nodelist: 节点列表

kv_map:属性及属性值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):

'''''改变/增加/删除一个节点的文本

nodelist:节点列表

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):

'''新造一个节点

tag:节点标签

property_map:属性及属性值map

content: 节点闭合标签里的文本内容

return 新节点'''

element = Element(tag, property_map)

element.text = content

return element

def add_child_node(nodelist, element):

'''''给一个节点添加子节点

nodelist: 节点列表

element: 子节点'''

for node in nodelist:

node.append(element)

def del_node_by_tagkeyvalue(nodelist, tag, kv_map):

'''''同过属性及属性值定位一个节点，并删除之

nodelist: 父节点列表

tag:子节点标签

kv_map: 属性及属性值列表'''

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)
