For your online store to work at its best, you must regularly monitor changes in the XML specifications of comparison engines. And it’s usually time-consuming. You can **reduce this time to a minimum** by using [Mergado Product XML](https://www.mergado.com/tag/mergado-product-xml).
function tableOfContents() {
return {
headings_menu: [],
heading_active: '', // Added to track the active section
shouldBeSticky: false,
generateToC() {
const headings = document.querySelectorAll('.js-article-full-headings h2, .js-article-full-headings h3');
let headingMap = {};
headings.forEach((heading) => { // Use an arrow function to maintain `this` context
// Normalize heading text to remove diacritics, then replace non-alphanumeric characters with dashes
var normalizedText = heading.textContent.normalize("NFD").replace(/[\u0300-\u036f]/g, ""); // Remove diacritics
var id = heading.id ? heading.id : normalizedText.trim().toLowerCase()
.split(' ').join('-').replace(/[^a-z0-9\-]/ig, ''); // Updated regex to replace non-alphanumeric characters
headingMap[id] = headingMap[id] !== undefined ? ++headingMap[id] : 0;
// Use the updated `id` with diacritics removed for the heading id and the TOC
const finalId = headingMap[id] ? `${id}-${headingMap[id]}` : id;
this.headings_menu.push({
id: finalId,
title: heading.textContent,
level: heading.tagName.toLowerCase(), // Track heading level
active: false, // Initially set active to false
});
heading.id = finalId;
});
},
checkStickyNeeded() {
const ul = this.$el.querySelector('ul');
if (ul) {
this.shouldBeSticky = ul.scrollHeight < window.innerHeight;
}
},
setActiveHeading() {
// disabled not working with active state on click
// add @scroll.window="setActiveHeading()" to the parent div
// const headings = document.querySelectorAll('.js-article-full-headings h2');
// let activeHeading = '';
// let closestHeadingDistance = Infinity;
// headings.forEach((heading) => {
// const rect = heading.getBoundingClientRect();
// const offset = rect.top - window.innerHeight / 2; // Consider heading in the middle of the screen as active
// if (offset < 0 && Math.abs(offset) < closestHeadingDistance) {
// activeHeading = heading.id;
// closestHeadingDistance = Math.abs(offset);
// }
// });
// // Update the active state in headings_menu
// if (activeHeading !== this.heading_active) {
// this.headings_menu = this.headings_menu.map(item => ({
// ...item,
// active: item.id === activeHeading,
// }));
// this.heading_active = activeHeading;
// }
},
setActiveItem(clickedId) {
this.headings_menu.forEach(item => {
item.active = (item.id === clickedId);
});
this.heading_active = clickedId; // Optionally update the heading_active property if used
},

For your online store to work at its best, you must regularly monitor changes in the XML specifications of comparison engines. And it’s usually time-consuming. You can **reduce this time to a minimum** by using [Mergado Product XML](https://www.mergado.com/tag/mergado-product-xml). With it, you **seamlessly convert data for all supported ad system formats**. See what’s new in its version 1.8.

## Mergado Product XML 1.8 clarifies the notation of numbers and adds new elements
See the [complete specification of version 1.8](https://www.mergado.com/sites/default/files/users/documents/shopsystems/mergado-product-xml-1-8-en.pdf). Here are some **key** **changes**:
### Writing numbers
- We have specified the way of writing numbers — we now introduce them as a **sequence of numbers without spaces or other characters**.
- Decimal numbers are separated by a decimal point.
- Mergado can continue to process various entries – for example, **single** **input** can help [macro](https://www.mergado.com/use-macros) authors.
### Element COST
- The new element COST indicates the **purchase price of products without VAT**, including storage costs, etc.
- It **calculates the margin**.
- It is designed both for the purchase price of goods and other direct costs, it is suitable for **pricing**.
### Element COST\_VAT
- The new element COST\_VAT is similar to the element COST, it states the value of the purchase price **including VAT**.
Use Mergado Product XML. When you learn your shop system to support this XML format, Mergado will **convert it to dozens of advertising systems**. Also, as a part of our tool, you get the chance to use advanced analytics or applications from the [Mergado Store](https://store.mergado.com/).
