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 will probably never have to construct a wxHtmlTag object
26yourself. Feel free to ignore the constructor parameters.
27Have a look at src/html/htmlpars.cpp if you're interested in creating it.
28
29\membersection{wxHtmlTag::GetAllParams}\label{wxhtmltaggetallparams}
30
31\constfunc{const wxString\&}{GetAllParams}{\void}
32
33Returns a string containing all parameters.
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
93Returns the value of the parameter. You should check whether the
94parameter exists or not (use \helpref{HasParam}{wxhtmltaghasparam}) first.
95
96\wxheading{Parameters}
97
98\docparam{par}{The parameter's name.}
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.}
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 wxChar *}{format}, \param{void *}{value}}
159
160This method scans given parameter. Usage is exactly the same as sscanf's
161usage except that you don't pass string but parameter name as the first parameter
162and that you can only retrieve one value (i.e. you can use only one "\%" element
163in {\it format}).
164
165
166\wxheading{Parameters}
167
168\docparam{par}{The name of tag you want to query}
169
170\docparam{format}{scanf()-like format string.}
171
172\docparam{value}{pointer to a variable to store value in }
