B4J Question how to read this xml file?

[Roberto P.]

Hello everybody
can someone tell me with which library I can read the attached file, which I cannot read with the libraries (xml sax and xmlmap)

Here is example

Dim aIS As InputStream = File.OpenInput(File.DirAssets,"county.xml")
    
    TR.Initialize(aIS)
    
'    TR.Initialize(File.OpenInput(File.DirAssets,"county.xml"))
    xml.Initialize
    xml.Parse2(TR,"Parser")

error:

Program started.

best xml library for me is this one:

SimpleXML2

This is an update to the SimpleXMl library I posted here; https://www.b4x.com/android/forum/threads/simplexml.75571/#post-748743 This update now allows reading and writing of XML files. The node traversal is now done via the XmlNodes so this is a new library. Example project attached. Quick...

Works fine here, tested with this code:

Sub AppStart (Args() As String)
    Dim x2m As Xml2Map
    x2m.Initialize
    Dim s As String = File.ReadString("C:\Users\H\Downloads\county.xml", "")
    Dim m As Map = x2m.Parse(s)
    Log(m.As(JSON).ToString)
End Sub

Note that the file starts with UTF8 BOM. This is a big mistake though it didn't cause any error when I test it.
You can remove the BOM character with:

s = s.Substring(1)
