The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Removing an XML node using xmlDocument and C#

Asked by wilfordrocks in XPath, C# Programming Language

Tags: xml, remove node

This is a minor problem, but if you have input I would appreciate it.
I want to remove all the nodes anywhere in an XML document that have element name No_export_rule.
The code below almost does this.  It removes all the attributes and so forth but leaves behind an empty element.  I would like to remove the elements rather than just empty them.
Thanks for your input.
//AFTER THE CODE RUNS
<No_Export_Rule>
    </No_Export_Rule>
    <No_Export_Rule>
    </No_Export_Rule>
    <No_Export_Rule>
    </No_Export_Rule>
//BEFORE THE CODE RUNS
<No_Export_Rule Lbl='Locality' Table='Report' Field='ORI_NO' Pl='0' Ctl='IDRTC_LOCALITY'><![CDATA[1005]]></No_Export_Rule>
<No_Export_Rule Lbl='Predominant Development Type' COPY='DEVEL' Table='Report' Field='HOW_RPTD' Pl='0' Ctl='IDRTC_PRED_DEV_TYPE'><![CDATA[1006]]></No_Export_Rule>
<No_Export_Rule COPY='E1' Table='Address' Row='Addrept' Field='ATNRBTW' Ctl='IDC_FTMILE_NODE_1'><![CDATA[In]]></No_Export_Rule>

            foreach (XmlNode node in nodes)
            {
               node.RemoveAll();this results in as bunch of empty nodes but the entry is still there
