Transferring value from one site to another?

Question

PHP

Good afternoon, there is a website that contains the latest prices for distributors of goods.
We want to make a configurator using these prices.
On the site, the price itself is displayed in a div there are:<div class="price-td">

<span data-currencyvalue="usd" class="js_price ">43.45</span>
<span data-currencysign="usd" class="js_sign ">$</span>

and a couple more span with parameters.
he himself <div>is in <td>, and he is in turn in <tr id="5968892" class="">
Correspondingly, we have a site on which there is an identified one <tr id="5968892" class="">for the corresponding product, it has a table, it does not have a variable "price" with the value that we need to get. The question is how to display it on another site? Perhaps there is some kind of reference that can display the final variable as a number<div class="price-td">

<span data-currencyvalue="usd" class="js_price ">43.45</span>

and its equivalent

<span data-currencysign="usd" class="js_sign "$/span>

.
In fact, there should be some kind of appeal to the site, with the search <div class="price-td">located in the <tr id="5968892" class="">
structure of the page with the product looks like this:

<tbody data-ajaxupdate="rows"><tr id="5968891" class="">
                                                <td>MOXA и ICP DAS</td>
                                                <td>42895</td>
                                                <td class="text-align-left-td product-title" title="Компьютер V2403-C3-T (CTO Models) x86 ready-to-run embedded computer with Intel Core i3 3217UE, 1 HD">Компьютер V2403-C3-T (CTO Models) x86 ready-to-run embedded computer with Intel Core i3 3217UE, 1 HD</td>

Answer 1

TheDarhi , the regular season will certainly be strange, but it should work
Next run through preg_match_all

Answer 2

Alternatively, you need to parse the data and enter it into your database in order to display it on your site, unless of course the site from which you want to receive data does not have an API, but in this case it is better to add the data to your database and then display it, for a number of reasons, for example, there may be a limit on the number of calls to the API.
