Subject: [WiX-users] Looking for a sample code for XML manipulation...
Preface: I found the sample located at
http://www.tramontana.co.hu/wix/lesson5.php#5.11 for manipulating XML
files and creating elements and assigning attribute values.
However, it does not quite cover our use case here.
Take this snippet of a web.config file:
<configuration>
<system.web>
<httpModules>
<add type="SomeNameSpace.Type1" name="Type1Handler"
/>
<add type="SomeNameSpace.Type2" name="Type2Handler"
/>
</httpModules>
</system.web>
</configuration>
We have code that will a WiX script, <wix:XmlFile Id="WCXml1"
File="[MODULETARGETDIR]web.config" Action="createElement" Name="add"
ElementPath="//configuration//system.web//httpModules" Sequence="1" />
that will add a new "add" element so that it looks like this:
<configuration>
<system.web>
<httpModules>
<add type="SomeNameSpace.Type1" name="Type1Handler"
/>
<add type="SomeNameSpace.Type2" name="Type2Handler"
/>
<add />
</httpModules>
</system.web>
</configuration>
Now we need to grab that new element and add the type and name attribute
values for it. There is probably an XPath construct for this, but I'm
not finding it at the moment.
Any help would be appreciated.
Thanks!
Rory
