@param encoding <str> - Specifies the document encoding. Default utf-8
- contains(self, em)
- Checks if #em is found anywhere within this element tree
@param em <AdvancedTag> - Tag of interest
@return <bool> - If element #em is within this tree

- feed(self, contents)
- feed - Feed contents. Use parseStr or parseFile instead.
@param contents - Contents
- filter(self, **kwargs)
- filter aka filterAnd - Filter ALL the elements in this DOM.
Results must match ALL the filter criteria. for ANY, use the *Or methods
Requires the QueryableList module to be installed (i.e. AdvancedHTMLParser was installed
without '--no-deps' flag.)
For alternative without QueryableList,
consider #AdvancedHTMLParser.AdvancedHTMLParser.find method or the getElement* methods
Special Keys:
tagname - The tag name
text - The inner text
@return TagCollection<AdvancedTag>
- filterAnd = filter(self, **kwargs)
- filter aka filterAnd - Filter ALL the elements in this DOM.
Results must match ALL the filter criteria. for ANY, use the *Or methods
Requires the QueryableList module to be installed (i.e. AdvancedHTMLParser was installed
without '--no-deps' flag.)
For alternative without QueryableList,
consider #AdvancedHTMLParser.AdvancedHTMLParser.find method or the getElement* methods
Special Keys:
tagname - The tag name
text - The inner text
@return TagCollection<AdvancedTag>
- filterOr(self, **kwargs)
- filterOr - Perform a filter operation on this node and all children (and their children, onto the end)
Results must match ANY the filter criteria. for ALL, use the *AND methods
For special filter keys, @see #AdvancedHTMLParser.AdvancedHTMLParser.filter
Requires the QueryableList module to be installed (i.e. AdvancedHTMLParser was installed
without '--no-deps' flag.)
For alternative, consider AdvancedHTMLParser.AdvancedHTMLParser.find method or the getElement* methods
@return TagCollection<AdvancedTag>
- find(self, **kwargs)
- find - Perform a search of elements using attributes as keys and potential values as values
(i.e. parser.find(name='blah', tagname='span') will return all elements in this document
with the name "blah" of the tag type "span" )
Arguments are key = value, or key can equal a tuple/list of values to match ANY of those values.
Append a key with __contains to test if some strs (or several possible strs) are within an element
Append a key with __icontains to perform the same __contains op, but ignoring case
Special keys:
tagname - The tag name of the element
text - The text within an element
NOTE: Empty string means both "not set" and "no value" in this implementation.
NOTE: If you installed the QueryableList module (i.e. ran setup.py without --no-deps) it is
better to use the "filter"/"filterAnd" or "filterOr" methods, which are also available
on all tags and tag collections (tag collections also have filterAllAnd and filterAllOr)

@param className <str> - A one-word class name
@param root <AdvancedTag/'root'> - Search starting at a specific node, if provided. if string 'root' [default], the root of the parsed tree will be used.
- getElementsByName(self, name, root='root')
- getElementsByName - Searches and returns all elements with a specific name.
@param name <str> - A string of the name attribute
@param root <AdvancedTag/'root'> - Search starting at a specific node, if provided. if string 'root' [default], the root of the parsed tree will be used.
- getElementsByTagName(self, tagName, root='root')
- getElementsByTagName - Searches and returns all elements with a specific tag name.
@param tagName <lowercase str> - A lowercase string of the tag name.
@param root <AdvancedTag/'root'> - Search starting at a specific node, if provided. if string 'root', the root of the parsed tree will be used.
- getElementsCustomFilter(self, filterFunc, root='root')
- getElementsCustomFilter - Scan elements using a provided function
@param filterFunc <function>(node) - A function that takes an AdvancedTag as an argument, and returns True if some arbitrary criteria is met
@return - TagCollection of all matching elements
- getElementsWithAttrValues(self, attrName, attrValues, root='root')
- getElementsWithAttrValues - Returns elements with an attribute, named by #attrName contains one of the values in the list, #values
@param attrName <lowercase str> - A lowercase attribute name
@param attrValues set<str> - A set of all valid values.
@return - TagCollection of all matching elements
- getFirstElementCustomFilter(self, filterFunc, root='root')
- getFirstElementCustomFilter - Scan elements using a provided function, stop and return the first match.
@see getElementsCustomFilter to match multiple elements
@param filterFunc <function>(node) - A function that takes an AdvancedTag as an argument, and returns True if some arbitrary criteria is met
@return - An AdvancedTag of the node that matched, or None if no match.
- getFormattedHTML(self, indent=' ')
- getFormattedHTML - Get formatted and xhtml of this document
@param indent - space/tab/newline of each level of indent, or integer for how many spaces per level
@return - Formatted html as string
- getHTML(self)
- getHTML - Get the full HTML as contained within this tree
@returns - String
- getRoot(self)
- getRoot - returns the root Tag.
NOTE: if there are multiple roots, this will be a special tag.
You may want to consider using getRootNodes instead if this
is a possible situation for you.
@return AdvancedTag
- getRootNodes(self)
- getRootNodes - Gets all objects at the "root" (first level; no parent). Use this if you may have multiple roots (not children of <html>)
Use this method to get objects, for example, in an AJAX request where <html> may not be your root.
Note: If there are multiple root nodes (i.e. no <html> at the top), getRoot will return a special tag. This function automatically
handles that, and returns all root nodes.
@return list<AdvancedTag> - A list of AdvancedTags which are at the root level of the tree.

Class methods inherited from AdvancedHTMLParser.Parser.AdvancedHTMLParser:
- createBlocksFromHTML(html, encoding='utf-8') from builtins.type
- createBlocksFromHTML - Returns the root level node (unless multiple nodes), and
a list of "blocks" added (text and nodes).
@return list< str/AdvancedTag > - List of blocks created. May be strings (text nodes) or AdvancedTag (tags)
NOTE:
Results may be checked by:
issubclass(block.__class__, AdvancedTag)
If True, block is a tag, otherwise, it is a text node
- createElementFromHTML(html, encoding='utf-8') from builtins.type
- createElementFromHTML - Creates an element from a string of HTML.
If this could create multiple root-level elements (children are okay),
you must use #createElementsFromHTML which returns a list of elements created.
@param html <str> - Some html data
@param encoding <str> - Encoding to use for document
@raises MultipleRootNodeException - If given html would produce multiple root-level elements (use #createElementsFromHTML instead)
@return AdvancedTag - A single AdvancedTag
NOTE: If there is text outside the tag, they will be lost in this.
Use createBlocksFromHTML instead if you need to retain both text and tags.
Also, if you are just appending to an existing tag, use AdvancedTag.appendInnerHTML
- createElementsFromHTML(html, encoding='utf-8') from builtins.type
- createElementsFromHTML - Creates elements from provided html, and returns a list of the root-level elements
children of these root-level nodes are accessable via the usual means.
@param html <str> - Some html data
@param encoding <str> - Encoding to use for document
@return list<AdvancedTag> - The root (top-level) tags from parsed html.
NOTE: If there is text outside the tags, they will be lost in this.
Use createBlocksFromHTML instead if you need to retain both text and tags.
Also, if you are just appending to an existing tag, use AdvancedTag.appendInnerHTML
