Python BeautifulSoup XML, AttributeError: can't set attribute, How to set to text attribute?

Question

我的 Xml 代码如下所示

<!-- ************************************************************************ -->
      <group title="Test procedure FBlock ablock">
        <case ident="Init" title="TS01 Activate" name="TC_Start_Application">
            <param name="Min" type="float">0.50
            </param>
            <param name="Max" type="float">5.00
            </param>
        </case>
      </group>

现在我可以像这样用 Beautiful soup 库读取 python 中 'param' 的文本属性：

TTgroup = re.compile('Test someword (.*?): .*')

with open(outFile) as fp:
    soup = BeautifulSoup(fp, "lxml")

groups=soup.find_all("group")
for group in groups:
    FBlk = group["title"]
    FBlk=TTgroup.search(FBlk)

cases = group.find_all("case")
for case in cases:
    casetitle = case["title"]
    method=str(re.sub(r'TS.*? ', '',casetitle))
    Fkt=method.split('.') # split at .
    Fkt=str(Fkt[0]) # Function ID from case
    method=re.sub('[ (){}<># .,-]', '', method)# Remove unwanted characters
    method=method.replace('0x', 'x') # Replace 0x to x

    Params = case.find_all("param")
    for Param in Params:
        if Param["name"] =="Min":
            Param.text ="&"+Param["name"]+";<!--"+Param.text+"-->"

但是，我无法更改参数的文本属性，并收到此错误消息

Param.text ="&"+Param["name"]+";<!--"+Param.text+"-->"
AttributeError: can't set attribute

Answer 1

text属性是read-only所以不能修改，但是可以修改string属性。
所以你可以改变 Tag 的文本内容，如果你替换 .text,

Param.text ="&"+Param["name"]+";<!--"+Param.text+"-->"

与 .string、

Param.string ="&"+Param["name"]+";<!--"+Param.text+"-->"
