### add(Node node) {#add-com.aspose.words.Node}
```
public void add(Node node)
```


Adds a node to the end of the collection.

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| node | [Node](../../com.aspose.words/node/) | The node to be added to the end of the collection. |

### clear() {#clear}
```
public void clear()
```


Removes all nodes from this collection and from the document.

 **Examples:** 

Shows how to remove all sections from a document.

```

 Document doc = new Document(getMyDir() + "Document.docx");

 // This document has one section with a few child nodes containing and displaying all the document's contents.
 Assert.assertEquals(doc.getSections().getCount(), 1);
 Assert.assertEquals(doc.getSections().get(0).getChildNodes(NodeType.ANY, true).getCount(), 17);
 Assert.assertEquals("Hello World!\r\rHello Word!\r\r\rHello World!", doc.getText().trim());

 // Clear the collection of sections, which will remove all of the document's children.
 doc.getSections().clear();

 Assert.assertEquals(0, doc.getChildNodes(NodeType.ANY, true).getCount());
 Assert.assertEquals("", doc.getText().trim());
 
```

### contains(Node node) {#contains-com.aspose.words.Node}
```
public boolean contains(Node node)
```


Determines whether a node is in the collection.

 **Remarks:** 

This method performs a linear search; therefore, the average execution time is proportional to [getCount()](../../com.aspose.words/nodecollection/\#getCount).

 **Examples:** 

Shows how to work with a NodeCollection.

```

 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);

 // Add text to the document by inserting Runs using a DocumentBuilder.
 builder.write("Run 1. ");
 builder.write("Run 2. ");

 // Every invocation of the "Write()" method creates a new Run,
 // which then appears in the parent Paragraph's RunCollection.
 RunCollection runs = doc.getFirstSection().getBody().getFirstParagraph().getRuns();

 Assert.assertEquals(2, runs.getCount());

 // We can also insert a node into the RunCollection manually.
 Run newRun = new Run(doc, "Run 3. ");
 runs.insert(3, newRun);

 Assert.assertTrue(runs.contains(newRun));
 Assert.assertEquals("Run 1. Run 2. Run 3.", doc.getText().trim());

 // Access individual runs and remove them to remove their text from the document.
 Run run = runs.get(1);
 runs.remove(run);

 Assert.assertEquals("Run 1. Run 3.", doc.getText().trim());
 Assert.assertNotNull(run);
 Assert.assertFalse(runs.contains(run));
 
```

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| node | [Node](../../com.aspose.words/node/) | The node to locate. |

**Returns:**
boolean -  true  if item is found in the collection; otherwise,  false .
### get(int index) {#get-int}
```
public Node get(int index)
```


Retrieves a building block at the given index.

 **Remarks:** 

The index is zero-based.

Negative indexes are allowed and indicate access from the back of the collection. For example -1 means the last item, -2 means the second before last and so on.

If index is greater than or equal to the number of items in the list, this returns a null reference.

If index is negative and its absolute value is greater than the number of items in the list, this returns a null reference.

 **Examples:** 

Shows ways of accessing building blocks in a glossary document.
