Android Question Read XML file

[jcmartini]

I wanted to read a simple xml file. I tried xmlsax with the following code:

Sub Parser_StartElement (Uri As String, Name As String, Attributes As Attributes)
Dim idx, Caption As String
'If Name = "Node" Then ' Begin @ idx=3
'If Name = "Items" Then ' Shows nothing
'If parser.Parents.IndexOf("Items") > -1 Then ' Begin @ idx=3
idx = Attributes.GetValue2("", "idx") ' Begin @ idx=1
Caption = Attributes.GetValue2("", "Caption")
ListView1.AddSingleLine(idx & " : " & Caption)
'End If
End Sub
Sub Parser_EndElement (Uri As String, Name As String, Text As StringBuilder)
End Sub

I cannot see the first zero idx. How should I do to have that ?

Another question: Where could I find XmlSax version 10 ?

You should use CODE /CODE tags when posting code. It makes it much easier to read.

I realise that I'm not really answering your quesiton directly, but it might be easier for you to switch to Xml2Map:

[B4X] Xml2Map - Simple way to parse XML documents

Nobody likes to parse XML. Parsing JSON is simple and fun. Parsing XML is tedious and boring. That is the reason behind the Xml2Map class. It internally parses the XML document and returns a Map with the parsed data. It is similar to parsing JSON. Tip: You can use this tool to help you with...

Xml2Map is the correct answer.

I saw a lot of posts which indicates that people has a lot of difficulties to solve their problems. Could you give me a simple example working with attributes ?

Are you using Xml2Map?

 

[jcmartini]

Yes, with Xml2Map. Thanks in advance.

Tips:
1. Use the GetElements sub from that post: https://www.b4x.com/android/forum/threads/b4x-xml2map-simple-way-to-parse-xml-documents.74848/
In retrospect it should have been part of the library.

2. The first thing that I like to do when parsing XML is to convert it to json and print it. It is simpler than it might sound:

Dim m As Map = xm.Parse(...)
Log(m.As(Json).ToString)

It helps understanding the structure.

About attributes:

If m.ContainsKey("Attributes") Then
 Dim attr As Map = m.Get("Attributes")
Log(attr)

I will try it. Thanks a lot.
