XmlDocument Vs StringBuilder

Hi Group,

You might have found the Title a little strange :); well following is
the problem description:
I want to form a SOAP xml request to a servlet, I have my Request xml
template ready.
Now I have following options:
1. Load the xml template in an XmlDocument object and manipulate it.
2. Load the xml template in a StringBuilder object, manipulate it and
then load it in XmlDocument.
3. Not using any template and creating the xml from scratch.
Following is the sample xml template which I will use:
<?xml version="1.0" encoding="UTF-8"?>
<MT_MaterialSearchRequest>
<!-- Customer Data -->
<CUSTOMERCUSTOMER _PLACEHOLDER</CUSTOMER>
<SALES_ORGSALES_ORG _ PLACEHOLDER </SALES_ORG>
<!-- Limit on the size of the search result -->
<DEFAULT_SORTINGDEFAULT_SORTING _PLACEHOLDER</DEFAULT_SORTING>
<!-- Material Data -->
<WIDTHWIDTH _HOLDER</WIDTH>
<SERIESERIE _HOLDER</SERIE>
<!-- Material List -->
<VISIBILITY_ITEM_IN>
<ITEM<!-NOTE: Number of <ITEMnodes is dynamic>
<MATERIAL></MATERIAL>
</ITEM>
<ITEM>
<MATERIAL></MATERIAL>
</ITEM>
</VISIBILITY_ITEM_IN>
</MT_MaterialSearchRequest>

My Questions:
1. For this scenario which of the above mentioned options which is
more suitable?
2. In General which options is more preferable?
3. I know that second option of using StringBuilder is going to be
very easy for implementation, but which option is better in terms of
speed of execution and memory considerations?

Hoping to get some expert comments on this :)

Thanks,

Rule #1
Don't use stringbuilder (or concat strings together before .NET) to build
XML.
Rule #2 See Rule #1.

Look for the XmlWriter class. This is your fastest... non-string-building
way to build xml.
