我尝试使用HTMLParser来解析以下HTML标记:
<input type="hidden" name="movingEventItemId" value="<dt:value property="movingEventItemId" javaScriptSafe="1"/>"/>
当我获得个别属性时,我希望它返回以下内容:
键入 - 隐藏
name - movingEventItemId
值 - &lt; dt:value property =&#34; movingEventItemId&#34; javaScriptSafe =&#34; 1&#34; /&GT;
但价值又回来了 - &lt; dt:value property =&#34; javascriptsafe =&#34; 1&#34; /&GT;
Python代码:
quote = '[\\\'\\"]'
class HiddenInputParser(HTMLParser):
def handle_starttag(self, tag, attrs):
if tag == 'input':
id = self.findAttr('id', attrs)
name = self.findAttr('name', attrs)
if not name and not id:
print('no name or id ' + self.get_starttag_text())
elif id is not None and name is not None and id != name:
print('id != name ' + self.get_starttag_text())
else:
id = (id if id else name)
output = '<input type="hidden" id="' + id + '" name="' + id + '" '
for attr in attrs:
key = attr[0]
if attr[1] and key != 'id' and key != 'name' and key != 'type':
matcher = re.search( key + '\\s*=\\s*(' + quote + ')', self.get_starttag_text(), re.IGNORECASE)
quote2 = matcher.group(1)
value = quote2 + attr[1] + quote2
output += ' ' + key + '=' + value
output += '/>'
print ( output )
else:
print ( self.get_starttag_text() )
def findAttr(self, id, attrs):
for attr in attrs:
if attr[0] == id:
return attr[1]
def fixHiddenInputs():
inputParser = HiddenInputParser()
files = []
for extension in extensions:
for root, dirnames, filenames in os.walk(path):
for filename in fnmatch.filter(filenames, extension):
for line in fileinput.input(os.path.join(root, filename), inplace=1):
line = line.rstrip()
if ( re.search( '<input.*type=' + quote + 'hidden' + quote, line ) ):
inputParser.feed(line)
else:
print( line)
def convertHiddenInputs():
pass
convertHiddenInputs()
fixHiddenInputs()
代码是在给定name属性值的情况下将id添加到输入标记。最终结果应如下所示:
<input type="hidden" id="displayOptions" name="displayOptions" value="<dt:value property="movingEventItemId" javaScriptSafe="1"/>"/>
这就是我得到的:
<input type="hidden" id="displayOptions" name="displayOptions" value="<dt:value property=" javascriptsafe="1"/>
答案 0 :(得分:0)
要为标记添加id
,不需要解析整行并获取每个属性。对于您的问题,更好的解决方案就是将id
添加到元素中,尽管其余的属性。如果您需要id
与name
相同,看起来您已经获得了name
属性。只需使用您获得的name
并在其之前或之后附加id="NAME_VALUE"
即可。
干杯!
