Thanks for the links, it really works!

I did everything as shown in the second link, but if there is a comma in the title everything breaks.

Is there a way to fix it?

Thank you for helping! In your example, a feed is generated for one category, I have a different situation

The category structure looks like this:
Leather chairs (category)
— product 1
— product 2
— product 3

Blue chairs (category)
— product 2
— product 4
“Product 2” is in 2 categories at once, and therefore the feed now displays it in the form

<offer id="182" available="true">
<url>https://.... </url>
<price>98</price>
<currencyId>USD</currencyId>
<categoryId>112</categoryId>
<categoryId>121</categoryId>
<name>product 2</name>
<picture>https://....jpg</picture>
</offer>

As you can see from the xml code, the codes for both categories are provided.

<categoryId>112</categoryId>
<categoryId>121</categoryId>

The site receiving the feed requires that each product have only one category specified. In my case, it doesn’t matter which category is indicated, the main thing is that each product has one category.

I need to leave only one category and exclude all others.

As a result I should get:

<offer id="182" available="true">
<url>https://.... </url>
<price>98</price>
<currencyId>USD</currencyId>
<categoryId>112</categoryId>
<name>product 2</name>
<picture>https://....jpg</picture>
</offer>

maybe I didn’t put it that way

There is a ready-made feed with many products, some products are included in several categories.

But the site for which this feed was created works according to the rules: 1 product = 1 category.

Can I leave only one category in this feed for products that have several categories?

Tell me please,

Which functions from the list do you recommend using in this case?

I’ll try to do
