For tags that have a name attribute, it will be set to the value of id if not provided explicitly:

Form(Button(target_id='foo', id='btn'),
     hx_post='/', target_id='tgt', id='frm')

<form hx-post="/" hx-target="#tgt" id="frm" name="frm">
  <button hx-target="#foo" id="btn" name="btn"></button>
</form>

fill_form

 fill_form (form:fastcore.xml.XT, obj)

Fills named items in form using attributes in obj

@dataclass
class TodoItem:
    title:str; id:int; done:bool; details:str
                
todo = TodoItem(id=2, title="Profit", done=True, details="Details")
check = Label(Input(type="checkbox", id="done", data_foo="bar"), "Done")
form = Form(Fieldset(Input(id="title"), check, Input(type="hidden", id="id"), Textarea(id='details'), Button("Save")))
form = fill_form(form, todo)
form

<form>
  <fieldset>
    <input id="title" name="title" value="Profit"></input>
    <label>
      <input type="checkbox" data-foo="bar" id="done" name="done" checked="1"></input>
Done
    </label>
    <input type="hidden" id="id" name="id" value="2"></input>
    <textarea id="details" name="details">Details</textarea>
    <button>Save</button>
  </fieldset>
</form>

fill_dataclass

 fill_dataclass (src, dest)

Modifies dataclass in-place and returns it

nt = TodoItem('', 0, False, '')
fill_dataclass(todo, nt)
nt

TodoItem(title='Profit', id=2, done=True, details='Details')

find_inputs

 find_inputs (e, tags='input', **kw)

def find_inputs(e, tags='input', **kw):
    # Recursively find all elements in `e` with `tags` and attrs matching `kw`
    if not isinstance(e, (list,tuple)): return []
    inputs = []
    if isinstance(tags,str): tags = [tags]
    elif tags is None: tags = []
    cs = e
    if isinstance(e, list):
        tag,cs,attr = e
        if e[0] in tags and kw.items()<=e[2].items(): inputs.append(e)
    for o in cs: inputs += find_inputs(o, tags, **kw)
    return inputs

find_inputs(form, id='title')

[['input', (), {'id': 'title', 'name': 'title', 'value': 'Profit'}]]

You can also use lxml for more sophisticated searching:

elem = lx.fromstring(to_xml(form))
elem.xpath("//input[@id='title']/@value")

['Profit']
