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)
