# Browser Mode

> [HTML Version](browsermodextext.htm)

XTEXT may be used as a very simple web browser, by specifying the TXFF\_HTML flag in the [TXC.DOCFMT'SRC](txc_docfmt-src.htm.md) field and setting the TXF\_READONLY flag. The usual source type options apply (TXFF\_STRING and TXFF\_FILE), except that in the TXFF\_FILE case, the filespec can also be a web-based URL. For web-based HTML documents and forms, the destination ([TXC.DOCFMT'DST](txc_docfmt-dst.htm.md)) must be a string/buffer.

In the case of a form, if the user clicks the SUBMIT button, XTEXT returns with exitcode=30 and the action, method, and data fields are output to the dst parameter in the following format:

\&url=<form url or filespec>\&action=actionstr\&method=

methstr\&name1=value1\&...\&nameN=valueN

The fields _actionstr_, _methstr_ and _nameN_ are as defined in the form itself. (_methstr_ will be GET or POST.) The _valueN_ fields return the data entered by the user in the form. (Checkbox and radio button fields return 0 or 1 to indicate empty or checked.) If a value contains the character "\&", the entire value string will be quoted. So you may want to use [STRTOK](strtok_sbr.htm.md) to simplify parsing the returned string.

**Notes**

•	Requires that the module hts13.dll be present in the bin directory, and that you use TXFF\_HTML with TXFF\_FILE in the TXC.DOCFMT'SRC or TXC.DOCFMT'DST fields. Only file mode is supported.

•	For browser mode, you must set TXF\_READONLY. Otherwise it will be in editing mode, similar to the existing RTF editing mode.

•	You must use TXF\_FITVIEW for all but the simplest files.

•	You may specify a web URL in the TXC.DOCFMT'SRC field, such as "http://www.microsabio.com". However, you may not output to a web address. (We recommend using .HTM as the extension for local HTML files.)

•	You can use the HTML format as simpler version of RTF with the goal of supporting just a few text attributes. To minimize the size of the outputted HTML file, you may want to set the TXC.HFLAGMASK and TXC.HFLAGS1 as follows:

TXC.hflagmask = \&h0001   \! Set/clear all flags from HFLAGS1

TXC.hflags1 = \&78006     \! strip out head, body, font, style tags
