This XQuery Module provides functions for converting HTML to XML. The input will only be converted if TagSoup is included in the classpath (see HTML Parsing for more details).
Conventions
All functions in this module are assigned to the http://basex.org/modules/html namespace, which is statically bound to the html prefix.
All errors are assigned to the http://basex.org/errors namespace, which is statically bound to the bxerr prefix.
Functions
html:parser
| Signatures | html:parser() as xs:string |
| Summary | Returns the name of the applied HTML parser (currently: TagSoup). If an empty string is returned, TagSoup was not found in the classpath, and the input will be treated as well-formed XML. |
html:parse
| Signatures | html:parse($input as xs:anyAtomicType) as document-node()html:parse($input as xs:anyAtomicType, $options as item()) as document-node() |
| Summary | Converts the HTML document specified by $input to XML, and returns a document node. The input may either be a string or a binary item (xs:hexBinary, xs:base64Binary). If the input is passed on in its binary representation, the HTML parser will try to automatically choose the correct encoding.The $options argument can be used to set TagSoup options. It can be specified
<html:options> <html:key1 value='value1'/> ... </html:options>
map { "key1" := "value1", ... }
|
| Errors | BXHL0001: the input cannot be converted to XML.

| Examples |
<html>

<a shape="rect" href="ok.html"/>
