B4J Question [SOLVED]XML Edit (convert to Map, edit then Back again or Edit XML directly)

[Peter Lewis]

Hi All, I am faced with a few choices , maybe more if you have one. I have a X<L file which has multiple lines of COLOR information, there can be any amount of lines from 1 to 30. I could take all the lines before and store it into a list and all the lines afterwards and store it into another list , generate the lines using code into a third list then when I write the xml file process the first list , then the third list and lastly the second list . OR write the changes into maps and convert the maps back into XML. Just extracting the areas for this was a long process.

Any suggestions ?

This is the XML code

This is the code i had to do to get to the lines of data required

Sub Button1_Click
    Dim map As Map
        map.Initialize

    Dim xm As Xml2Map
        xm.Initialize
  
    map = xm.Parse(File.ReadString(File.DirAssets, "data.xml"))
  
    Dim attr As Map = map.Get("mad_storage_place")
    Dim bttr As Map =  attr.Get("place")
    Dim cttr As Map = bttr.Get("effect")
    Dim dttr As Map = cttr.Get("facade")
    Dim ettr As Map = dttr.Get("renderer")
    Dim fttr As Map = ettr.Get("effect_feature_color_list")
    Dim gttr As Map = fttr.Get("color_list")
    Dim httr As List = gttr.Get("color")
    For x = 0 To httr.Size-1
        Log("=============== "& x &" ================")
      
        Dim final As Map = httr.Get(x)
        Dim valu As Map = final.Get("Attributes")
  
            For i = 0 To valu.Size - 1
                Log("Key: " & valu.GetKeyAt(i))
                Log("Value: " & valu.GetValueAt(i))
            Next
        Log("=======================================")
    Next
  
End Sub

This was the result

Would probably make it easier for people to try if you posted the xml as text, else they would need to type it all in.

If you are able to generate this XML with Xml2Map then this will be the best option. Read the XML. Modify the lists / maps and write it back.

Xml2Map

XMLBuilder

The Library is Xml2Map. It is a b4xlib
Inside it there is a Class Map2Xml which uses - internally - XmlBuiler.

Map2Xml - New class!

Map2Xml converts the map created with Xml2Map to a Xml string. It uses XmlBuilder library and it is compatible with B4A, B4i and B4J.
It can be used to modify existing XML documents. You read the document with Xml2Map, make the changes in the returned map and write it back with Map2Xml.

Just to clarify the libraries involved.
