8This class represents a single HTML tag.
9It is used by \helpref{tag handlers}{handlers}.

22
23\func{}{wxHtmlTag}{\param{const wxString\& }{source}, \param{int }{pos}, \param{int }{end\_pos}, \param{wxHtmlTagsCache* }{cache}}
24
25Constructor. You'll probably never have to construct a wxHtmlTag object
26yourself. Feel free to ignore the constructor parameters.
27Have a look at lib/htmlparser.cpp if you're interested in creating it.
28
29\membersection{wxHtmlTag::GetAllParams}\label{wxhtmltaggetallparams}
30
31\constfunc{const wxString\&}{GetAllParams}{\void}
32
33Returns string with all params.
34
35Example : tag contains {\tt <FONT SIZE=+2 COLOR="\#000000">}. Call to
36tag.GetAllParams() would return {\tt SIZE=+2 COLOR="\#000000"}.
37
38
39\membersection{wxHtmlTag::GetBeginPos}\label{wxhtmltaggetbeginpos}
40
41\constfunc{int}{GetBeginPos}{\void}
42
43Returns beginning position of the text {\it between} this tag and paired
44ending tag.
45See explanation (returned position is marked with `|'):
46
47\begin{verbatim}
48bla bla bla <MYTAG> bla bla intenal text</MYTAG> bla bla
49 |
50\end{verbatim}
51
52
53\membersection{wxHtmlTag::GetEndPos1}\label{wxhtmltaggetendpos1}
54
55\constfunc{int}{GetEndPos1}{\void}
56
57Returns ending position of the text {\it between} this tag and paired
58ending tag.
59See explanation (returned position is marked with `|'):
60
61\begin{verbatim}
62bla bla bla <MYTAG> bla bla intenal text</MYTAG> bla bla
63 |
64\end{verbatim}
65
66
67\membersection{wxHtmlTag::GetEndPos2}\label{wxhtmltaggetendpos2}
68
69\constfunc{int}{GetEndPos2}{\void}
70
71Returns ending position 2 of the text {\it between} this tag and paired
72ending tag.
73See explanation (returned position is marked with `|'):
74
75\begin{verbatim}
76bla bla bla <MYTAG> bla bla intenal text</MYTAG> bla bla
77 |
78\end{verbatim}
79
80\membersection{wxHtmlTag::GetName}\label{wxhtmltaggetname}
81
82\constfunc{wxString}{GetName}{\void}
83
84Returns tag's name. The name is always in uppercase and it doesn't contain
85'<' or '/' characters. (So the name of {\tt <FONT SIZE=+2>} tag is "FONT"
86and name of {\tt </table>} is "TABLE")
87
88
89\membersection{wxHtmlTag::GetParam}\label{wxhtmltaggetparam}
90
91\constfunc{wxString}{GetParam}{\param{const wxString\& }{par}, \param{bool }{with\_commas = FALSE}}
92
93Retuns the value of the parameter. You should check whether the
94param exists or not (use \helpref{HasParam}{wxhtmltaghasparam}) first.
95
96\wxheading{Parameters}
97
98\docparam{par}{The parameter's name in uppercase}
99
100\docparam{with\_commas}{TRUE if you want to get commas as well. See example.}
101
102\wxheading{Example}
103
104\begin{verbatim}
105...
106/* you have wxHtmlTag variable tag which is equal to
107 HTML tag <FONT SIZE=+2 COLOR="#0000FF"> */
108dummy = tag.GetParam("SIZE");
109 // dummy == "+2"
110dummy = tag.GetParam("COLOR");
111 // dummy == "#0000FF"
112dummy = tag.GetParam("COLOR", TRUE);
113 // dummy == "\"#0000FF\"" -- see the difference!!
114\end{verbatim}
115
116\membersection{wxHtmlTag::HasEnding}\label{wxhtmltaghasending}
117
118\constfunc{bool}{HasEnding}{\void}
119
120Returns TRUE if this tag is paired with ending tag, FALSE otherwise.
121
122See the example of HTML document:
123
124\begin{verbatim}
125<html><body>
126Hello<p>
127How are you?
128<p align=center>This is centered...</p>
129Oops<br>Oooops!
130</body></html>
131\end{verbatim}
132
133In this example tags HTML and BODY have ending tags, first P and BR
134doesn't have ending tag while the second P has. The third P tag (which
135is ending itself) of course doesn't have ending tag.
136
137\membersection{wxHtmlTag::HasParam}\label{wxhtmltaghasparam}
138
139\constfunc{bool}{HasParam}{\param{const wxString\& }{par}}
140
141Returns TRUE if the tag has parameter of the given name.
142Example : {\tt <FONT SIZE=+2 COLOR="\#FF00FF">} has two parameters named
143"SIZE" and "COLOR".
144
145\wxheading{Parameters}
146
147\docparam{par}{the parameter you're looking for. It must {\it always} be in uppercase!}
148
149\membersection{wxHtmlTag::IsEnding}\label{wxhtmltagisending}
150
151\constfunc{bool}{IsEnding}{\void}
152
153Returns TRUE if this tag is ending one.
154({\tt </FONT>} is ending tag, {\tt <FONT>} is not)
155
156\membersection{wxHtmlTag::ScanParam}\label{wxhtmltagscanparam}
157
158\constfunc{wxString}{ScanParam}{\param{const wxString\& }{par}, \param{const char *}{format}, fuck}
159
160This method scans given parameter. Usage is exactly the same as sscanf's
161usage except that you don't pass string but param name as the first parameter.
162
163\wxheading{Parameters}
164
165\docparam{par}{The name of tag you want to query (in uppercase)}
166
167\docparam{format}{scanf()-like format string.}
168
169\wxheading{Cygwin and Mingw32}
170
171If you're using Cygwin beta 20 or Mingw32 compiler please remember
172that ScanParam() is only partially implemented! The problem is
173that under Cygnus' GCC vsscanf() function is not implemented. I worked around
174this in a way which causes that you can use only one parameter in ...
175(and only one \% in {\it format}).
