我们有一个使用JSF的Java项目。在我们的视图层中，我们没有在所有XHTML文件中使用id。我想要做的是解析XHTML文件并检查标签
<h:inputText id="username" value="#{identity.username}"/>
The constant part is <h:input...> The rest can be anything like <h:inputSecret <h:inputWHATELSE after selecting the correct tag. I want to check if there is an id attribute of that tag. If not, I want to add an id to it.
常量部分是
Here is one of our XHTML files.
这是我们的XHTML文件之一。
I tried to do the work with Python. I tried ElementTree, piksemel and BeautifulSoup. Any help about this issue will be appreciated.

Using Beautifulsoup, you could do this as follows:
使用Beautifulsoup，你可以这样做：
from BeautifulSoup import BeautifulSoup
import re
soup = BeautifulSoup(<your_xml_here>)
nodes = soup.findAll(name=re.compile('^h:input'))
for node in nodes:
if 'id' not in dict(node.attrs):
node['id'] = <whatever you need>
As it can be seen, to get all the nodes that match the name pattern you're looking for all you need is a regular expression. After that, you can check the node attributes to make sure if id is defined or not and assign a new value when needed.
可以看出，要获得所有与您正在寻找的名称模式匹配的节点，您需要的是一个正则表达式。之后，您可以检查节点属性以确定是否定义了id，并在需要时分配新值。
