Server Behaviors 189
These shortened search patterns are flexible, so the user can add to the code. However, if the
server behavior changes the URL, when the user clicks OK, the participant is replaced, and the
customizations are lost. To update more precisely, add an
updatePatterns tag that contains a
pattern for updating each parameter:
<updatePatterns>
<updatePattern paramNames="rs">/(\b)\w+(\.EOF)/¬
</updatePattern>
<updatePattern paramNames="new__url">
/(Response\.Redirect\(")[^\r\n]*(")/i
</updatePattern>
</updatePatterns>
In update patterns, the parentheses are reversed and are placed around the text before and after
the parameter. For search patterns, use
textBeforeParam(param)textAfterParam. For update
patterns, use
(textBeforeParam)param(textAfterParam). All the text between the two
parenthetical subexpressions is replaced with the new value for the parameter.
Deleting server behaviors
Default deletion and dependency counts The user can delete an instance that is selected in the
Server Behaviors panel by clicking the minus (-) button or pressing Delete. All the participants are
removed except for the ones that are shared by other server behaviors. Specifically, if more than
one server behavior has a participant pointer to the same node, the node is not deleted.
By default, participants are deleted by removing an entire tag. If the insert location is
"wrapSelection", only the outer tag is removed. For attributes, the entire attribute declaration is
removed. The following example shows an attribute participant on the
ACTION attribute of
a
form tag:
<form action="<% my_participant %>">
After deleting, only <form> remains.
Using delete flags to limit participant deletion There might be cases where you want to limit the
way that participants are deleted. This can be achieved by adding a delete tag to the EDML file.
The following example shows a participant that is an
href attribute of a link:
<a href="<%=MY_URL%>">Link Text</a>
When this attribute participant is deleted, the resulting tag is <a>Link Text</a>, which no
longer appears as a link in Dreamweaver. It might be preferable to delete only the attribute value,
which can be done by adding the following tag to the participant EDML file:
<delete deleteType="innerOnly"/>
Another approach is to remove the entire tag when the attribute is deleted by typing <delete
deleteType="tagOnly"/>
, and the resulting text is Link Text.
