There is another XML plugin (by Instructor) you can try: http://nsis.sourceforge.net/XML_plug-in

I found it useful.

Sorry, but with this plugin, i don't arrive to simple add a Node in an empty XML

${xml::LoadFile} "$INSTDIR\addons.xml" $0
${xml::CreateNode} '<addon nom="Test">test</addon>'
${xml::SaveFile} "$INSTDIR\addons.xml" $0
${xml::Unload}

I think you left out the file var in the createnode command:

${xml::CreateNode} '<addon nom="Test">test</addon>' $0

(I haven't tested this, just read the docs.)

${xml::CreateNode} only creates the node in memory and returns its handle. You need to use this handle value with another function to get this new node into the file:

${xml::InsertAfterNode}
${xml::InsertBeforeNode}
${xml::InsertEndChild}
${xml::ReplaceNode}

For example:

${xml::CreateNode} '<addon nom="Test">test</addon>' $1
${xml::ReplaceNode} "$1" $0

Ok thanks but if my XML doesn't have Node and Child in the XML File,
${xml::InsertAfterNode}
${xml::InsertBeforeNode}
${xml::InsertEndChild}
${xml::ReplaceNode}
can not introduce my Node, no ?
So how can I do?

Thanks for your help

Are you trying to use the XML plugin to create an XML file?

The author of the XML plugin suggests using FileWrite commands to create an XML file. You only need to create a small XML file then you can use the XML plugin to add things to it or change things in it. Here is a code fragment that creates a small XML file and then modifies it.


  FileOpen $R9 "addons.xml" w
  FileWrite $R9 "<config><local>Dummy</local></config>"
  FileClose $R9
  
  ${xml::LoadFile} "addons.xml" $0
  ${xml::RootElement} $1 $0
  ${xml::CreateNode} '<addon nom="Test">test</addon>' $1
  ${xml::InsertEndChild} "$1" $0
  ${xml::SaveFile} "addons.xml" $0
  
  ${xml::Unload}

This creates a file called addons.xml then modifies it to end up like this:


<config>
    <local>Dummy</local>
    <addon nom="Test">test</addon>
</config>

Ok thanks you, i understood

I would like to know if it's possible to make a search into XML

For example, before to add my addon in the XML file, I would like to be sure that it is not already into.
I don't know if it's possible

Yes, you can search it. There are some examples in the XMLTest.nsi script supplied with the plugin and the documentation gives details of the various ways to search/goto something in the XML file.

There are a couple of pages discussing the XML plugin here: http://forums.winamp.com/showthread....hreadid=227162
