Reading an xml string - .NET Framework

JRD

Greetings,

I would like to search down through the following xml string that is returned to my calling app via a webservice.
What I am trying to get is the following section from the xml string

<component><sec tion><code code="8716-3" codeSystem="2.1 6.840.1.113883. 6.1" codeSystemName= "LOINC" displayName="Vi talSigns" /><title>Vital Signs</title><text><ta ble><thead><tr> <th>Date</th><th>Descript ion</th><th>Test</th><th>Result</th></tr></thead><tbody><t r><td rowspan="5">17 Nov 2006 03:39 PM</td><td rowspan="5">rec orded by: jmedici</td></tr><tr><td>BP SYS</td><td>120 mm Hg LUE, Standing</td></tr><tr><td>BP DIAS</td><td>60 mm Hg LUE, Standing</td></tr><tr><td>PUL RATE</td><td>60 bpm L Carotid</td></tr><tr><td>PUL QUAL</td><td>Irregula r</td></tr></tbody></table></text></section></component>

And this is how I am trying to do it: (any help would be appreciated

Dim xpathDoc As Xml.XPath.XPath Document
Dim xmlNavigator As Xml.XPath.XPath Navigator

Dim xmlNI As Xml.XPath.XPath NodeIterator

Try

xpathDoc = New Xml.XPath.XPath Document(TextBo x1.Text)

With xpathDoc

xmlNavigator = .CreateNavigato r

xmlNI = xmlNavigator.Se lect("")

While (xmlNI.MoveNext )

MsgBox(xmlNI.Cu rrent.Name & "=" & xmlNI.Current.V alue)

End While

End With

xmlNI = Nothing

xmlNavigator = Nothing

xpathDoc = Nothing

Catch ex As Exception

Label1.Text = ex.Message

End Try

the xml

It looks like you're trying to iterate through the entire document's nodes, matching it yourself when you find it. A more direct route would be to reference the specific node you want via XPath:
myNavigator.Sel ect("//ClinicalDocumen t/Component[Section/Code/@Code='10164-2']")

This says "select the ClinicalDocumen t/Component node whose Section/Code subnode has an attribute where @Code='10164-2'
