// Assume the attributes object contains all the attributes of an XML element int numAttrs = attributes.count();
QString attrValue = attributes.value("attrName");
QString attrValue = attributes.value(index);This example shows how to use the `value()` method of `QXmlAttributes` to get the value of an attribute by its index. Overall, the Qt Xml module provides a convenient and easy-to-use API for parsing and manipulating XML data in C++.
