Method Summary

Modifier and Type	Method	Description
boolean	equals(Object o)
List<HtmlParseNode>	getInnerContent()	The inner content is the data between the opening and closing tags of this element, comprised of potentially other complex elements and/or characters or a mix (or nothing at all, which will return an empty list).
TagInfo	getTagInfo()	Returns the TagInfo, which contains valuable information like the type of element (p, a, div, and so on) and attributes like class, id, etc.
String	getTextContent()	If the ParseNodeType is ParseNodeType.CHARACTERS, then this will have text content.
ParseNodeType	getType()	Gets the type of this node - either it's an element, with opening and closing tags and attributes and an inner content, or it's just plain text.
int	hashCode()
String	innerText()	Return the inner text of a node
List<String>	print()	Return a list of strings of the text content of the tree.
List<HtmlParseNode>	search(TagName tagName, Map<String,String> attributes)	Return a list of HtmlParseNode nodes in the HTML that match provided attributes.

Constructor Details

HtmlParseNode

public HtmlParseNode(ParseNodeType type,
 TagInfo tagInfo,
 List<HtmlParseNode> innerContent,
 String textContent)

Method Details

print

public List<String> print()

Return a list of strings of the text content of the tree.

This method traverses the tree from this node downwards, adding the text content as it goes. Its main purpose is to quickly render all the strings out of an HTML document at once.

search

public List<HtmlParseNode> search(TagName tagName,
 Map<String,String> attributes)

Return a list of HtmlParseNode nodes in the HTML that match provided attributes.

getType

public ParseNodeType getType()

Gets the type of this node - either it's an element, with opening and closing tags and attributes and an inner content, or it's just plain text.

getTagInfo

public TagInfo getTagInfo()

Returns the TagInfo, which contains valuable information like the type of element (p, a, div, and so on) and attributes like class, id, etc.

getInnerContent

public List<HtmlParseNode> getInnerContent()

The inner content is the data between the opening and closing tags of this element, comprised of potentially other complex elements and/or characters or a mix (or nothing at all, which will return an empty list).

getTextContent

public String getTextContent()

If the ParseNodeType is ParseNodeType.CHARACTERS, then this will have text content. Otherwise, it returns an empty string.

innerText

public String innerText()

Return the inner text of a node

If this element has only one inner content item, and it's a ParseNodeType.CHARACTERS element, return its text content.

If there is more than one node, concatenates them to a single string, with each section wrapped in square brackets.
