XML Parse error

[Ercüment USTA]

Dear Sirs,

We are using Delphi 10.2 and C++ Builder 10.2 Update 3 and we have upgraded to kbmMW 5.10.10 from version 5.02.10.
But we have problems in parsing the XMLs including CDATA when using the new version.

The XML samples we couldn’t parse are below:
1.
<root>
<item>
<![CDATA[ if ( x < y ) then x = y ]]>
</item>
</root>

2.
<root>
<item>
<fxml>
<![CDATA[ <root><item><script><![CDATA[ if ( x < y ) then x = y ]]></script></item></root> ]]>
</fxml>
</item>
</root>

The function we are trying to read:
bool __fastcall ReadDynFiles(TMemoryStream *ms)
{
TkbmMWCustomDOMXMLParser* ADOM = new TkbmMWCustomDOMXMLParser();
bool Ret = true;

try {
ms->Position = 0;
ADOM->SetStream(ms);
try {
ADOM->Parse(); <<<<<<<<<< KBMMW_ERR_TRANSPORT_XML_INVALIDFORMAT
CreateDynObjects(ADOM->Root->Nodes->Nodes[0]);
} catch(Exception &e) {
if (FbxLogView) FbxLogView(“Parse Error : ” + ServiceErrorTable(e.HelpContext) + e.Message);
Ret = false;
}
} __finally {
delete ADOM;
}
return Ret;
}

On the function “procedure PushNode(const ANode:TkbmMWDOMXMLNode);” in the kbmMWXML.pas source code, it gives the error
“kbmMWRaiseException(KBMMW_ERR_TRANSPORT_XML_INVALIDFORMAT,’Mismatched open and closing tag names’);”

There is no problem in the old version, we are facing the problem in the new one.

Thank you in advance,

Hi,

I can confirm a bug in kbmMW’s CDATA parser. It is fixed in next release.

Regarding your 2nd example. Nesting CDATA is not allowed in XML, why that will fail regardless.

best regards
