XmlSax incompatible with accented characters in file. Xml

[BluSky76]

Just a single accented letter to crash the control XmlSax. If you replace the line <title> Phone library was updated - V1.10 </ title> with the line <title> Phone library was updated - V1.10à </ title> procedure returns error

Sub Parser_EndElement (Uri As String, Name As String, Text As StringBuilder)
If parser.Parents.IndexOf ("item")> -1 Then
If Name = "title" Then
Title = Text.ToString
Else if name = "link" Then
Link Text.ToString
Else If Name = "pubDate" Then
pubDate = Text.ToString
end If
end If
If Name = "item" Then
ListView1.AddSingleLine2 (Title, Link) 'add the title as the text and the link as the value
end If

the error applies to each character type: à or ì

:signOops:
Someone has a solution?

Here:

As this file is not encoded in the default encoding (UTF8). You should use a TextReader and specify its encoding:

   'parse the xml file
   Dim in As InputStream
   in = File.OpenInput(File.DirAssets, "rss.xml")
   Dim tr As TextReader
   tr.Initialize2(in, "ISO-8859-1")
   parser.Parse2(tr, "Parser")
   in.Close

Error compiling code

I tried yesterday with this method but I always have the following error:

Compiling code. 0.02
Generating R file. 0.00
Compiling generated Java code. Error
B4A line: 49
parser.Parse2(readXml, \
javac 1.6.0_30
src\readXml\xmlsax\main.java:276: cannot find symbol

location: class anywheresoftware.b4a.objects.SaxParser
_parser.Parse2((java.io.Reader)(_readxml.getObject()),"Parser");
^
1 error

 

[Erel]

Can you post the code that caused this error?

Java compiled

I simply replaced in XmlSax.zip on the forum, with the lines:

'parse the xml file
'Dim in As InputStream
'in = File.OpenInput(File.DirAssets, "rss.xml")
'parser.Parse(in, "Parser")
'in.Close

'parse the xml file
Dim in As InputStream
in = File.OpenInput(File.DirAssets, "rss.xml")
Dim readXml As TextReader
readXml.Initialize2(in, "ISO-8859-1")
parser.Parse2(readXml, "Parser")
in.Close

May be incompatible with Java 1.6.30?

May be incompatible with Java 1.6.30?

No, it is not related to Java version.

Try to run the attached program.

Sorry does not work. Usually error when compiling

Seems to be a problem with your Basic4android installation.

Unzip the attached zip file and copy both files to the internal libraries folder.
Right click on the list of libraries and choose refresh.

 

[BluSky76]

OK

It now works.

You can encode the writing?

It can decode written?

example file rss.xml
L&amp;rsquo;

original characters
L '

Thank you.

 

[Erel]

The escaped entities should be decoded automatically by the XML parser.

 

[BluSky76]

I did not understand what you mean.

If there are 12 rows in the listview (item) and can make sure that if I click on one that is highlighted. I tried ListView1.SingleLineLayout.Label.Enabled = false but is still selected. I would like clicking on a line that is evident only if Position is with an even number

Erel,
using the library does not decode this XmlSax characters you enclose the link text and returns a result and not a illegibile.

XmlSax returns

&agrave;

and not

à

There is a solution to the problem?

thanks

 

[Erel]

Please post an XML file which demonstrates this problem (you will need to zip it before uploaing).

 

[BluSky76]

xmlsax

As you can see it does not convert accented letters

 

[Erel]

Seems to work fine. It unescapes the xml entities:

The original xml is:
