I am working on asp.net application. I have a function like this:
Public Function ExtractText(node As XmlNode) As String
End Function
I need to pass following XML as input to above function:
<myrequirements Id="7743" Type="tcg_Concept20_sc_323256419566173_context" StartNode="2724" EndNode="2869">

I'm tryign to read a specific attribute from a xml website using this code:
'this is the url im trying to read, tmpIn is a string that complete the url:
Dim url As String = "http://maps.google.com/maps/geo?q=" & tmpIn & "&output=xml"
Dim reader As New XmlTextReader(url)
[Code]....
The problem is tmpIn takes diferents values (string) when the function is used and sometimes this works, and othertimes it gives an error (Invalid character in the given encoding. Line 9, position 15.), but is not because of the url, is when it tries to read the coordinates...
I am using VB.NET to read an XHTML file. I need my program to find every element within the XML structure which has the "class" attribute set to a specific value.IE: I need an array (or similar list) of all elements from the document which contain class="mytag".There is a list of several values I need to detect, all of which start with the same word 'mytag' followed by another word - so using a "contains" function seems sensible here
View 2 RepliesI'm using HtmlAgilityPack to parse HTML. I want to check if an element has a specific attribute. I want to check whether an <a> tag has the href attribute.
Dim doc As HtmlDocument = New HtmlDocument()

Dim root As HtmlNode = doc.DocumentNode
Dim anchorTags As New List(Of String)
For Each link As HtmlNode In root.SelectNodes("//a")
If link.HasAttributes("href") Then doSomething() 'this doesn't work because hasAttributes only checks whether an element has attributes or not

I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .
