HTML Parser

Go to Product

This HTML parser is based on

Quotation from the web page: The HTML Parser is an implementation of the HTML5 parsing algorithm in Java. The parser is designed to work as a drop-in replacement for the XML parser in applications that already support XHTML 1.x content with an XML parser and use SAX, DOM or XOM to interface with the parser. Low-level functionality is provided for applications that wish to perform their own IO and support document.write() with scripting. The parser core compiles on Google Web Toolkit and can be automatically translated into C++. (The C++ translation capability is currently used for porting the parser for use in Gecko.)

You can supply input to this node in a variety of formats:

  • HTTP Result cells which you obtained with the “HTTP Retriever” node
  • Binary data cells
  • String cells which contain a local file: URL; note that although technically possible, it is not recommended to input http: or https: URLs directly into the parser. Use the “HTTP Retriever” for downloading instead and input the HTTP Results into this node to guarantee proper encoding.
  • String cells which contain the raw markup (e.g. <html><head> […] )

“Infotising”: This node is only intended for “static” HTML structures. If you need to work with interactive web pages and web apps which are dynamically generated client-side in the browser, have a look at our plugin “Selenium Nodes”.


Column in the input table which holds the data to parse.
Drop input column
Enable to exclude the input column from the result table.
Make absolute URLs
When enabled, all relative URLs in the document are converted to absolute ones. This simplifies/permits further processing steps with the URLs obtained from the document.

Input Ports

Input table containing (X)HTML data to be parsed.

Output Ports

Output table with parsed (X)HTML documents appended. In case, a document could not be parsed, a “missing value” is appended.
