How importxml google sheets Can use * in class substring value [@class='myClassValue--&"*"']? Forexfactory

I'm trying to import all at once the values from a class split in 3 subclasses.

The class was subdivided into 3 'subclasses' substrings values appended "--low", "--medium", "--high" like so:

<td class="calendar__cell calendar__impact impact calendar__impact calendar__impact--low">

<td class="calendar__cell calendar__impact impact calendar__impact calendar__impact--medium">

<td class="calendar__cell calendar__impact impact calendar__impact calendar__impact--high">

I tried the working solution for each separated class below:

My Xpath query for the 1st class which returns all the 'low' tagged titles successfully:

//td[@class='calendar__cell calendar__impact impact calendar__impact calendar__impact--low']//span/@title

My google sheets formula:

=IMPORTXML("https://www.forexfactory.com/calendar?month=jul.2023",a1)

The screenshot:

What I want to do is get all elements from those 3 classes all at once.

I though of using a regular expression all operator "*" but I'm not sure how to formulate it.

I thought of this formula but it's not there yet:

//td[@class='calendar__cell calendar__impact impact calendar__impact calendar__impact--&"*"']//span/@title

I found this working workaround with contains:

//tbody//span/@title[contains(.,'Impact')]

But I'm interested in knowing how a regular expression all operator "*" way with the 3 classes queried at once would work.

I previously tested those other queries inspired by @Tanaike
answer

//table//span/@title	

//tbody//span/@title	

//tr//span/@title	

//tbody//img/@src

If my understanding is correct, I'm worried that in this case, a
value like calendar__impact--* might not be able to be used. In this case, how about using contains and or as follows?

Modified formula:

In this case, the URL (https://www.forexfactory.com/calendar?month=jul.2023) is put into cell "A1".

=IMPORTXML(A1,"//td[contains(@class,'calendar__impact--low') or contains(@class,'calendar__impact--medium') or contains(@class,'calendar__impact--high')]//span/@title")

or

=IMPORTXML(A1,"//td[contains(@class,'low') or contains(@class,'medium') or contains(@class,'high')]//span/@title")

or, in your HTML, the following xpath might be able to be used.

=IMPORTXML(A1,"//td[contains(@class,'calendar__impact--') and not(contains(@class,'holiday'))]//span/@title")

Testing:

When the above formula is used, the following result is obtained. The cells "A2" and "B2" have the 1st and 2nd formula, respectively.
