Android Tutorial XML Parsing with the XmlSax library

[MikieK]

Sorry

:sign0013: Obviously I didn't take into consideration that the file may change when I unmount my SDcard. Sorry for wasting your time.

What's the user-agent and can it be changed?

maximum file size for parser?

Hi I've been using the parser to read in an xml file and write the contents to the app's database.

Its all been working fine however I've noticed if the xml file goes over a critical filesize that the parser fails with at the line

parser.Parse2(reader,"Parser")

with 'LastException - java.io.IOException'

The conditions under which this happens is when the filesize of the source xml file approaches 1MB. I can't find anything about this limitation though in the documentation, can someone explain what I'm doing wrong?

Thanks
John

It's probably this Android limitation.

 

[yonson]

thanks for the prompt reply, if I understand correctly then the necessary step is to rename the file as a 'jpg' and then it will read in ok?

I saw Erel has mentioned this on another forum

Hi, Erel!

I have XML :

<?xml version="1.0" encoding="utf-8" ?> 
 <string xmlns="http://tempuri.org/">test</string>

How do I get the string "test"?

This library is only available for users who have bought Basic4android. Please contact support@basic4ppc.com if you have bought Basic4android.

List to XML

Hi Erel,

Is there any way to generate XML directly from a list of map objects?

Thanks,
Koushik

 

[Erel]

Currently there is no automatic way to do it. You can generate JSON with the JSON library.
It shouldn't be hard to write a code that generates the required XML. Especially if the values do not need to be encoded.

XML parsing directly

Hi all, i'm new to Basic4Android, i need to figure out how to parse XML information when retrieved directly from a URI Address, i've seen examples here that do this but using a saved file, i need to do it directly after receiving the information from the HTTP client, any help will be greatly appreciated guys

Regards,
Walter Flores

Download the data with HttpUtils and then get the InputStream with HttpUtils.GetInputStream. The parsing step itself is identical.

Trouble with dual TAG

Hello,

Using this fine library I have a little problem.

The main TAG is also used within a SUBTAG. This causes every line twice within my ListView.

XML:
<?xml version="1.0" encoding="windows-1252"?>
<!--DVD Profiler Collection Export-->
<Collection>
<DVD>
<ProfileTimestamp>2008-12-26T18:18:53.000Z</ProfileTimestamp>
<ID>0044005373028.9</ID>
<MediaTypes>
<DVD>true</DVD>
<HDDVD>false</HDDVD>
<BluRay>false</BluRay>
</MediaTypes>
<UPC>0-044005-373028</UPC>
<CollectionNumber>658</CollectionNumber>
<CollectionType>Owned</CollectionType>
<Title>Het Meisje met het Rode Haar</Title>
<DistTrait/>
<OriginalTitle/>
<CountryOfOrigin>Netherlands</CountryOfOrigin>
<ProductionYear>1981</ProductionYear>
<Released>2001-09-05</Released>
<RunningTime>109</RunningTime>
<RatingSystem>Videovoorlichtingsysteem</RatingSystem>
<Rating>12</Rating>
</DVD>

Source:

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

Can someone tell me how to prevent this behaviour?

Thanks,
André

 

[Erel]

Try this:

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

Issues Parsing XML from HTTP Response

Hello, I'm not sure where the issues is. This snippets is from a program that attempts to parse a Yahoo API response. Many posts have shown that this should work. However, I continue to get a Null Value exception: :sign0104:

java.lang.NullPointerException

Sub find_Bars(lat,lon As String)
    Dim request As HttpRequest
   URL = "http://local.yahooapis.com/LocalSearchService/V3/localSearch?appid=YahooDemo"
    request.InitializeGet(URL & "&query=bar" & "&results=20" & "&radius=10" & "&latitude=42.53" & "&longitude=-83.73")
   request.Timeout = 10000
    If HttpClient1.Execute(request, 1) = False Then Return 
End Sub
Sub HttpClient1_ResponseSuccess (Response As HttpResponse, TaskId As Int)
Dim result As InputStream
result = Response.GetInputStream
parser.Parse(result, "Parser")
End Sub
'Sub HttpClient1_ResponseSuccess (Response As HttpResponse, TaskId As Int)
'Dim result As String
'result = Response.getstring("UTF8")
'Log(result)
'End Sub

When the second sub HttpClient1_ResponseSuccess is substituted, the xml response is returned correctly.

Thanks for your help.

Found it...
I hadn't initialized the parser. My bad...

Need parsing help

Hi There,

I am trying to parse craigslist phoenix | internet engineering jobs search " "

But getting continuous error, can anyone guide me with some code sample?

Thanks in advance.

Regards,
KS

 

[stevel05]

I have not looked at parsing, so probably can't help with that. But if you post your project (zipped) those that could help you would have a starting point without having to re-invent the wheel. And may be able to find a problem with your code without having to do too much work.

And you could have a solution in less time.

 

[neelmon]

Thanks for your quick reply.

I have used the following code for testing:

Sub Parser_EndElement (Uri As String, Name As String, Text As StringBuilder)
If Parser.Parents.IndexOf("item") > -1 Then
Log(Name & "-->" & Text)
End If
End Sub

After one iteration, its giving an error at following line:

parser.Parse(resultString,"Parser")

Error Details:
org.apache.harmony.xml.ExpatParser$ParseException: At line 86, column 0: not well-formed (invalid token)

At this point LOG is showing:


title-->Senior ASP.NET/SQL Server Developer (I-10 &amp; Elliott)
link-->Senior ASP.NET/SQL Server Developer

I dont know if these details will help you to identify the problem.
