Re: Appending elements using XPathNavigator LookupNamespace and the dreaded and embeded reference to [xsi:type=""]

Hmm I think the answer is related to something like:

XmlAttribute nsAttribute = doc.CreateAttribute("type", "xx", "tns:SalgGassGevinstdelingType");newElement.Attributes.Append(nsAttribute);

Appending elements using XPathNavigator LookupNamespace and the dreaded and embeded reference to [xsi:type=""]

Hello,

While hosting an INFOPATH file in a c# WINFORM application, I'm having a problem referencing the XML namespaces below (the last XML example).
Well, better stated, I'm having an issue trying to INSERT the snippet below.

The [xsi:type=""] reference is I think is giving me an issue

But before I deal refer to my diffucult snippet, here's one that is relatively easy to insert (well, easy now !)

<tns:grunnlagsdata>
<tns:grunnlagsdataverdi>
    <gass:fraDato>2012-07-05</gass:fraDato>
    <gass:tilDato>2012-07-05</gass:tilDato>
    <gass:verdi>123</gass:verdi>
    <gass:kommentar>abc</gass:kommentar>
</tns:grunnlagsdataverdi>
<tns:grunnlagsdataverdi>
    <gass:fraDato>2012-07-19</gass:fraDato>
    <gass:tilDato>2012-07-21</gass:tilDato>
    <gass:verdi>456</gass:verdi>
    <gass:kommentar>xyz</gass:kommentar>
</tns:grunnlagsdataverdi>
</tns:grunnlagsdata>

It's easy because the code to look up the namespaces, similar to this, does the job nicely.

private bool FindInfoPathNamespace(string ns)
{
var navigator2 = formControl1.XmlForm.MainDataSource.CreateNavigator();
var namespaceName2 = string.Empty;
var foundNamespace2 = false;
if (navigator2.MoveToFirstChild())
{
    namespaceName2 = navigator2.LookupNamespace(@"xmlns:" + ns);
    while (namespaceName2 == null || namespaceName2.Length <= 0)
    {
      if (!navigator2.MoveToNext())
        break;
      namespaceName2 = navigator2.LookupNamespace(ns);
    };
}
if (namespaceName2 != null && namespaceName2.Length > 0)
    foundNamespace2 = true;
else
    foundNamespace2 = false;
}

(code above is hacked a little just for clarity)

In each case, I can pass the Namespace Prefixs to the function and get the full path - in the case of either of these (tns / gass).
And the code to create and insert the element might go like this, after I've populated (tns / gass):

XmlNode grunnlagsdataverdi = doc.CreateElement("tns", "grunnlagsdataverdi", tns);

XmlNode field = doc.CreateElement("gass", "fraDato", gass);

XmlNode node = grunnlagsdataverdi.AppendChild(field);

node.InnerText = "2012-01-01";

field = doc.CreateElement("gass", "tilDato", gass);

node = grunnlagsdataverdi.AppendChild(field);

node.InnerText = "2012-01-02";

field = doc.CreateElement("gass", "verdi", gass);

node = grunnlagsdataverdi.AppendChild(field);

node.InnerText = "996";

field = doc.CreateElement("gass", "kommentar", gass);

node = grunnlagsdataverdi.AppendChild(field);

node.InnerText = "I did it!";

doc.AppendChild(grunnlagsdataverdi);

var space = "xyz";// abbreviated for clarity.

formControl1.XmlForm.MainDataSource.CreateNavigator().SelectSingleNode(space,

NamespaceManager).AppendChild(doc.DocumentElement.CreateNavigator());

But the example below really sends me for a whirl - not really sure how to pull the namespaces , I suspect, because of xsi:type="" references.

<tns:salg xsi:type="tns:SalgGassGevinstdelingType">
<gass:levertMengde>
    <type:levertMengdePerDag>
      <type:leveringsDato>2012-07-12</type:leveringsDato>
      <type:levertMengdePaaDag>123</type:levertMengdePaaDag>
    </type:levertMengdePerDag>
    <type:levertMengdePerDag>
      <type:leveringsDato>2012-07-19</type:leveringsDato>
      <type:levertMengdePaaDag>545</type:levertMengdePaaDag>
    </type:levertMengdePerDag>
</gass:levertMengde>
</tns:salg>

Appreciate your assistance, thanks!
