How to write out special character.
Hi every body,
I have one problem with Install program. I have tried a lot but i can't solve it; I need helping.
My problem is:
In my install script i uses "XML.DLL" plug-in to access ".xml" file. The code is:

xml::LoadFile /NOUNLOAD "$INSTDIR\Config.xml" .r0

xml::CreateNode /NOUNLOAD "<DataPath>M:\M&V\Data</DataPath>" .R0

xml::FindNextElement /NOUNLOAD "ProjectfilePath" .r0 .r1

xml::ReplaceNode /NOUNLOAD "$R0" .r0

xml::SaveFile "$INSTDIR\Config.xml" .r0

i want to set node <DataPath> with the value is M:\M&V\Data but the problem occur with the result. The character "&" can not be appeared in the result.
The result is : M:\MV\Data
I don't know how to write the character "&" output. I have try to use $\&, &amp;, hexa code ... but it still disappeared.

This is an XML issue, not NSIS. The problem is that the & character is a special character. Use &amp;amp; instead. For example:
xml::CreateNode /NOUNLOAD "<DataPath>M:\M&amp;amp;V\Data</DataPath>" .R0

Oh Yes. I had tried that case too. But the result was:<DataPath>M:\M&amp;V\Data</DataPath>.
"&amp;" appeared instead "&". I don't know why.
My xml file is encoded in ANSI; Does it effect the result.
("xml.dll" i'm using is version 1.5)

The fact that you are using ANSI shouldn't matter.

But maybe the text is being parsed twice. So you need something like: &amp;amp;amp;
