Hi,

has someone allready thinked about #PB_ReFormat using FormatXML and the way the output looks like?

Example:

<?xml version="1.0" encoding="UTF-8"?>
<gwcore>
  <module name="gwpp" load="true">
    <test.test>
      some text
    </test.test>
    <test.long>
      299 
    </test.long>
  </module>
</gwcore>

The problem is GetXMLNodeText will return all spaces and new lines, it is a bit stupid for loading a formated saved xml with pb again and work with.

A formated xml output (like ie or firefox displays) like this whould be better in my opinion.

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<gwcore>
  <module name="gwpp" load="true">
    <test.test>some text</test.test>
    <test.long>299</test.long>
  </module>
</gwcore>

what are you guys think about?

A small workaround:

Code: Select all

Procedure SaveBeautifyXML(XMLId.l, XMLFile$)
  Protected i, Lpos, Rpos = 1, pos = 1, indent = 0, tag$ = "", ntag, xml$, new$, encoding$
  If IsXML(XMLId)
    xml$ = Space(ExportXMLSize(XMLId))
    ExportXML(XMLId, @xml$, Len(xml$))
    xml$ = RemoveString(xml$, Chr(13))
    For i=1 To CountString(xml$, "<")
      Lpos = FindString(xml$, "<", Rpos)
      Rpos = FindString(xml$, ">", Lpos)
      ntag$ = Mid(xml$,Lpos, Rpos-Lpos+1)
      If tag$="" ; <?xml version="1.0" encoding="UTF-8"?>
        new$ = ntag$
        If FindString(ntag$, "UTF-8",1)
          encoding$ = "UTF-8"
        EndIf
        indent - 2
      ElseIf Left(tag$,2) <> "</" And Left(ntag$,2) = "</" ; <Tag></Tag>
        txt$ = Trim(Mid(xml$, pos, Lpos-pos))
        If Left(txt$,1) = #LF$
          txt$ = Trim(Mid(txt$,2))
        EndIf
        If Right(txt$,1) = #LF$
          txt$ = Trim(Left(txt$,Len(txt$)-1))
        EndIf
        new$ + txt$ + ntag$ 
      Else
        If Left(tag$,2) = "</" And Left(ntag$,2) = "</" ;  ; </Tag2></Tag1>
          indent - 2
        ElseIf Left(tag$,2) <> "</" And Left(ntag$,2) <> "</" ;  ; <Tag1><Tag2>
          indent + 2
        EndIf
        new$ + #LF$ + Space(indent) + ntag$
      EndIf
      tag$ = ntag$
      pos = Rpos+1
    Next
    If CreateFile(0, XMLFile$)
      If encoding$ = "UTF-8"
        WriteStringFormat(0, #PB_UTF8)
        WriteString(0, new$, #PB_UTF8)
      Else
        WriteString(0, new$)
      EndIf
      CloseFile(0)
    EndIf
  EndIf
EndProcedure


If LoadXML(1, "address.xml")
  SaveBeautifyXML(1, "adress.xml")
  FreeXML(1)
EndIf

Before:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<Adressen Anzahl="1">
  <Adresse id="1">
    <Name>
      Thorsten Hoeppner
    </Name>
    <Strasse>
      Alte Zeile 18
    </Strasse>
    <Ort>
      87600 Kaufbeuren
    </Ort> 
  </Adresse>
</Adressen>

After:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<Adressen Anzahl="1">
  <Adresse id="1">
    <Name>Thorsten Hoeppner</Name>
    <Strasse>Alte Zeile 18</Strasse>
    <Ort>87600 Kaufbeuren</Ort>
  </Adresse>
</Adressen>

I'm supporting this feature request.

However, another workaround is, instead of using

Code: Select all

text$ = GetXMLNodeText(*node)

use something like this

Code: Select all

#WHITESPACE$ = " " + #TAB$ + #CRLF$

Procedure.s TrimChars (source$, charList$=#WHITESPACE$)
   ; in : string
   ; out: string without any leading or trailing characters,
   ;      that are contained in 'charList$'
   Protected left, right, length=Len(source$)

   ; Trim left
   left = 1
   While (left <= length) And FindString(charList$, Mid(source$,left,1), 1)
      left + 1
   Wend

   ; Trim right
   right = length
   While (left < right) And FindString(charList$, Mid(source$,right,1), 1)
      right - 1
   Wend

   ProcedureReturn Mid(source$, left, right-left+1)
EndProcedure

text$ = TrimChars(GetXMLNodeText(*node))

I've just needed to use this formatting, however have had one problem.
When a tag is followed directly by its close tag (i.e. is empty), the output is changed to <Tag/> when I would like the old <Tag></Tag>

Code: Select all

<String id="Author"></String>

becomes

Code: Select all

<String id="Author"/>

I've looked at the code, but cannot see how it's eliminating the end tag.

Can anyone help?[/code]

Please try this code.

That code didn't work either.

Here's a shortened orig input file (It's appears as one long line in a xml file)

Code: Select all

<?xml version="1.0" encoding="ISO-8859-1"?><Template><Version>1.0</Version><Page><Name>A4</Name><Properties><String id="Author"></String><String id="Width">297.000000MM</String><String id="Height">210.000000MM</String></Properties><Content></Content></Page></Template>

Now here's the output from that code

Code: Select all

<?xml version="1.0" encoding="ISO-8859-1"?>
<Template>
   <Version>1.0</Version>
   <Page>
      <Name>A4</Name>
      <Properties>
         <String id="Author"/>
         <String id="Width">297.000000MM</String>
         <String id="Height">210.000000MM</String>
      </Properties>
      <Content/>
   </Page>
</Template>

Notice the <string id="Author"/> and the <Content/> tags.

Here's what I need as the result.

Code: Select all

<?xml version="1.0" encoding="ISO-8859-1"?>
<Template>
  <Version>1.0</Version>
  <Page>
    <Name>A4</Name>
    <Properties>
      <String id="Author"></String>
      <String id="Width">297.000000MM</String>
      <String id="Height">210.000000MM</String>
    </Properties>
  <Content></Content>
</Page>
</Template>

Any help will be appreciated.

It's some time ago when I dealt with this stuff ...
Well, I see the problem now: The combination of PB's LoadXML() and ExportXML() does the unwanted conversion. Fortunately, for your problem at hand we do not need it anyway.

So please see my new procedure FormatXMLfile() here.

That does it.

Thanks Little John
