+\membersection{wxHtmlTag::GetAllParams}\label{wxhtmltaggetallparams}
-\constfunc{wxString}{GetName}{\void}
+\constfunc{const wxString\&}{GetAllParams}{\void}
-Returns tag's name. The name is always in uppercase and it doesn't contain
-'<' or '/' characters. (So the name of {\tt <FONT SIZE=+2>} tag is "FONT"
-and name of {\tt </table>} is "TABLE")
+Returns a string containing all parameters.
+Example : tag contains {\tt <FONT SIZE=+2 COLOR="\#000000">}. Call to
+tag.GetAllParams() would return {\tt SIZE=+2 COLOR="\#000000"}.
-\membersection{wxHtmlTag::HasParam}\label{wxhtmltaghasparam}

-Example : {\tt <FONT SIZE=+2 COLOR="\#FF00FF">} has two parameters named
-"SIZE" and "COLOR".
+\constfunc{int}{GetBeginPos}{\void}
-\wxheading{Parameters}
+Returns beginning position of the text {\it between} this tag and paired
+ending tag.
+See explanation (returned position is marked with `|'):

-\constfunc{wxString}{GetParam}{\param{const wxString\& }{par}, \param{bool }{with\_commas = FALSE}}
+\constfunc{int}{GetEndPos1}{\void}
-Retuns the value of the parameter. You should check whether the

+\constfunc{int}{GetEndPos2}{\void}
+
+Returns ending position 2 of the text {\it between} this tag and paired

+\membersection{wxHtmlTag::GetName}\label{wxhtmltaggetname}
+\constfunc{wxString}{GetName}{\void}
-\membersection{wxHtmlTag::ScanParam}\label{wxhtmltagscanparam}
+Returns tag's name. The name is always in uppercase and it doesn't contain
+'<' or '/' characters. (So the name of {\tt <FONT SIZE=+2>} tag is "FONT"
+and name of {\tt </table>} is "TABLE")
-\constfunc{wxString}{ScanParam}{\param{const wxString\& }{par}, \param{const char *}{format}, fuck}
-This method scans given parameter. Usage is exatly the same as sscanf's
-usage except that you don't pass string but param name as the first parameter.
+\membersection{wxHtmlTag::GetParam}\label{wxhtmltaggetparam}
+
+\constfunc{wxString}{GetParam}{\param{const wxString\& }{par}, \param{bool }{with\_commas = false}}
+
+Returns the value of the parameter. You should check whether the
+parameter exists or not (use \helpref{HasParam}{wxhtmltaghasparam}) first.
\wxheading{Parameters}
-\docparam{par}{The name of tag you wanna query (in uppercase)}
+\docparam{par}{The parameter's name.}
-\docparam{format}{scanf()-like format string.}
+\docparam{with\_commas}{true if you want to get commas as well. See example.}
-\wxheading{Cygwin and Mingw32}
+\wxheading{Example}
-If you're using Cygwin beta 20 or Mingw32 compiler please remember
-that ScanParam() is only partially implemented!! The problem is
-that under Cygnus' GCC vsscanf() function is not implemented. I workarounded
-this in a way which causes that you can use only one parameter in ...
-(and only one \% in {\it format})
+\begin{verbatim}
+...
+/* you have wxHtmlTag variable tag which is equal to
+ HTML tag <FONT SIZE=+2 COLOR="#0000FF"> */
+dummy = tag.GetParam("SIZE");
+ // dummy == "+2"
+dummy = tag.GetParam("COLOR");
+ // dummy == "#0000FF"
+dummy = tag.GetParam("COLOR", true);
+ // dummy == "\"#0000FF\"" -- see the difference!!

-\membersection{wxHtmlTag::GetAllParams}\label{wxhtmltaggetallparams}
+\membersection{wxHtmlTag::GetParamAsColour}\label{wxhtmltaggetparamascolour}
-\constfunc{const wxString\&}{GetAllParams}{\void}
+\constfunc{bool}{GetParamAsColour}{\param{const wxString\& }{par}, \param{wxColour *}{clr}}
-Returns string with all params.
+Interprets tag parameter {\it par} as colour specification and saves its value
+into wxColour variable pointed by {\it clr}.
-Example : tag contains {\tt <FONT SIZE=+2 COLOR="\#000000">}. Call to
-tag.GetAllParams() would return {\tt SIZE=+2 COLOR="\#000000"}.
+Returns true on success and false if {\it par} is not colour specification or
+if the tag has no such parameter.
-\membersection{wxHtmlTag::IsEnding}\label{wxhtmltagisending}
+\membersection{wxHtmlTag::GetParamAsInt}\label{wxhtmltaggetparamasint}
-\constfunc{bool}{IsEnding}{\void}
+\constfunc{bool}{GetParamAsInt}{\param{const wxString\& }{par}, \param{int *}{value}}
-Returns TRUE if this tag is ending one.
-({\tt </FONT>} is ending tag, {\tt <FONT>} is not)
+Interprets tag parameter {\it par} as an integer and saves its value
+into int variable pointed by {\it value}.
+Returns true on success and false if {\it par} is not an integer or
+if the tag has no such parameter.
\membersection{wxHtmlTag::HasEnding}\label{wxhtmltaghasending}
\constfunc{bool}{HasEnding}{\void}
-Returns TRUE if this tag is paired with ending tag, FALSE otherwise.
+Returns true if this tag is paired with ending tag, false otherwise.
See the example of HTML document:
doesn't have ending tag while the second P has. The third P tag (which
is ending itself) of course doesn't have ending tag.

-\constfunc{int}{GetEndPos2}{\void}
+This method scans the given parameter. Usage is exactly the same as sscanf's
