</m:getlistofalllatestvariantsresponse> </env:body> </env:envelope> i extract values variantid, productcode, name child nodes node "variant".
all did using xml binding wizard wrapper unit , threw xmldocument component in form.
my code far parse 'productcode':
procedure tform1.parsexml(const axmltext: string); var envelopetype: ixmlenvelopetype; productcode: string; begin xmldocument1.xml.text := axmltext; envelopetype := getenvelope(xmldocument1); productcode := envelopetype.body.getlistofalllatestvariantsresponse.result.variant.productcode.text; memo2.text := 'product code: ' + productcode; end; the problem is, everytime empty string value required node values.
due poor implementation of xml namespaces in delphi's txmlnodelist, code produced xml binding wizard can not work correctly. because root element carries namespace, code assumes have same namespace on childnodes. has side effect xml code can't find correct node when namespace changes case m:getlistofalllatestvariantsresponse. fail understand why has been implemented can have multiple namespaces on childnodes.
you can fix following these steps:
1) copy files xml.xmldoc.pas , xml.xmldom.pas source directory project directory , include them in project
2) modify local xml.xmldoc.pas file
change function function txmlnodelist.findnode(nodename: domstring): ixmlnode;
function txmlnodelist.findnode(nodename: domstring): ixmlnode; begin result := findnode(nodename, defaultnamespaceuri); // --> add these lines below // node not found default namespace, fallback blank namespace if not assigned(result) result := findnode(nodename, ''); end; 3) modify local xml.xmldom.pas file
change function nodematches this:
function nodematches(const node: idomnode; const tagname, namespaceuri: domstring): boolean; begin result := ((namespaceuri = '') or (samenamespace(node, namespaceuri)) or (node.namespaceuri= '')) , ((node.nodename = tagname) or (node.localname = tagname)); end; 4) modify unit generated xml binding wizard
we must reflect fact getlistofalllatestvariantsresponse node uses namespace:
procedure txmlbodytype.afterconstruction; begin registerchildnode('getlistofalllatestvariantsresponse', txmlgetlistofalllatestvariantsresponsetype, 'http://www.posti-care_suite.posti.nokia.com/posti_caresuite_interface.wsdl'); inherited; end;
