contains method

contains(node)

Determines whether a node is in the collection.

def contains(self, node: aspose.words.Node):
    ...

Parameter	Type	Description
node	Node	The node to locate.

Remarks

This method performs a linear search; therefore, the average execution time is proportional to NodeCollection.count.

Returns

True if item is found in the collection; otherwise, False.

Examples

Shows how to work with a NodeCollection.

doc = aw.Document()
builder = aw.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.
runs = doc.first_section.body.first_paragraph.runs
self.assertEqual(2, runs.count)
# We can also insert a node into the RunCollection manually.
new_run = aw.Run(doc=doc, text='Run 3. ')
runs.insert(3, new_run)
self.assertTrue(runs.contains(new_run))
self.assertEqual('Run 1. Run 2. Run 3.', doc.get_text().strip())
# Access individual runs and remove them to remove their text from the document.
run = runs[1]
runs.remove(run)
self.assertEqual('Run 1. Run 3.', doc.get_text().strip())
self.assertIsNotNone(run)
self.assertFalse(runs.contains(run))
