You can manually place XML content in your document layout by dragging elements from the Structure pane to the page or to existing frames. When you place an element, its child elements (and all child elements below those, if any) are placed as well.
In the Structure panel, a structure-specific blue diamond appears on an element’s icon if the element has been placed in the document; elements that haven’t been placed show an unplaced icon.
Drag the element onto the page. InDesign creates a frame for the element.
Drag the element onto an existing frame. If the frame contains content, it is replaced by content from the XML data.
Map XML tags to paragraph and character styles.
Apply styles to elements.
Format the selected content manually by choosing text options in the Control panel.
