aspose.words 获取当前节点的标题

获取当前节点(例如段落或表格)的标题,您可以使用Aspose.Words API中的HeadingLevel属性。该属性返回一个整数,指示当前节点所在的标题级别。例如,如果节点是一级标题,则HeadingLevel属性返回1,如果节点是二级标题,则返回2,以此类推。
以下是获取当前节点标题级别的C#代码示例:
```
Document doc = new Document("input.docx");
Node currentNode = doc.CurrentNode;
if (currentNode != null && currentNode.NodeType == NodeType.Paragraph)
{
Paragraph currentParagraph = (Paragraph)currentNode;
int headingLevel = currentParagraph.ParagraphFormat.StyleIdentifier - (int)StyleIdentifier.Heading1 + 1;
Console.WriteLine("Current node is a heading of level " + headingLevel);
}
```
这个示例会输出当前节点(如果它是一个段落)的标题级别。请注意,我们使用ParagraphFormat.StyleIdentifier属性来确定当前段落的样式,然后从Heading1样式的标识符中减去该值,以确定当前段落的标题级别。

aspose.words 获取当前节点的二级标题
要获取当前节点的二级标题,您可以使用Aspose.Words API中的Range类来查找当前节点之前的所有标题,并筛选出标题级别为2的标题。
以下是获取当前节点之前的二级标题文本的C#代码示例:
```
Document doc = new Document("input.docx");
Node currentNode = doc.CurrentNode;
if (currentNode != null && currentNode.NodeType == NodeType.Paragraph)
{
Paragraph currentParagraph = (Paragraph)currentNode;
// Find all paragraphs before the current paragraph with heading level 2
NodeCollection headings = doc.GetChildNodes(NodeType.Paragraph, true);
List<string> secondLevelHeadings = new List<string>();
foreach (Paragraph heading in headings)
{
if (heading.ParagraphFormat.StyleIdentifier == StyleIdentifier.Heading2 &&
heading.Range.EndOffset < currentParagraph.Range.StartOffset)
{
secondLevelHeadings.Add(heading.GetText());
}
}
// Output the text of the last second-level heading found
if (secondLevelHeadings.Count > 0)
{
Console.WriteLine("The most recent second-level heading is: " + secondLevelHeadings[secondLevelHeadings.Count - 1]);
}
else
{
Console.WriteLine("No second-level headings found before the current node.");
}
}
```
这个示例会输出当前节点之前的所有二级标题中最新的一个。请注意,我们使用ParagraphFormat.StyleIdentifier属性来确定段落的样式,然后筛选出标题级别为2的段落,并且只考虑在当前段落之前的标题。
aspose.words 通过section获取当前节点的标题
要通过节(Section)获取当前节点的标题,您可以使用Aspose.Words API中的Section类来获取当前节点所在的节,然后使用该节的Header或Footer属性来获取标题。
以下是通过节获取当前节点标题的C#代码示例:
```
Document doc = new Document("input.docx");
Node currentNode = doc.CurrentNode;
if (currentNode != null && currentNode.NodeType == NodeType.Paragraph)
{
Paragraph currentParagraph = (Paragraph)currentNode;
// Get the section that contains the current node
Section section = currentParagraph.GetAncestor<Node>(NodeType.Section) as Section;
if (section != null)
{
// Get the header of the section
HeaderFooter header = section.HeadersFooters[HeaderFooterType.HeaderPrimary];
if (header != null)
{
// Output the text of the header (assuming it contains a title)
Console.WriteLine("The header of the current section is: " + header.GetText());
}
else
{
Console.WriteLine("No header found for the current section.");
}
}
else
{
Console.WriteLine("The current node is not in a section.");
}
}
```
这个示例会输出包含当前节点的节的标题。请注意,我们使用Paragraph.GetAncestor方法来获取当前节点的祖先节,然后使用Section.HeadersFooters属性和HeaderFooterType.HeaderPrimary枚举值来获取节的主标题。如果找不到标题,则会输出相应的消息。
