Hi Group, sorry, i have to bother you with a problem i can't resolve by myself.
Environment: Visual Studio 6.0 Xerces-C 2.5.0 (Windows Binaries downloaded from xml.apache.org) What i want my program to do: I have a XML-File with placeholders in the attribute-values and textnode-values (call it a template). I get some data (not XML, a tag=value format) from another application. I load the data and parse it. Then i load my XML-File with a DOMBuilder and parse it too. Then i traverse the DOMTree with a DOMNodeIterator and look for the special placeholders. replacing the right data from the tag/value file for the placeholder. After i processed the last node i want to write the DOMTree to another XML-Document with a DOMWriter (now not anymore a template, now it is a XML-File with Data instead). Nodes which are not used in this replacing process (no data transferred from the other application for this unique placeholder) are removed from the tree as it is not neccessary for this document. Maybe in another run with other data transferred it is used of course. So my template includes many nodes only sometimes used and sometimes not. I hope you get the idea! What my problem is: Most of all works very fine and fast (Thx. to the great people her which creates this great XERCES-Parser) But! When i look at my Data-XML-File after processing and serializing i notice some blank lines and spaces outside the nodes (not in the nodes - in the nodes all is as i wish). I noticed further that the amount of spaces/lines between the outputted nodes is somehow dependent on how much nodes i removed between the two outputted nodes. Let me show you a little snippet from my "template" and my outputted "datafile" to clear things up: ------------SNIP-TEMPLATE-------------- <?xml version="1.0" encoding="iso-8859-1"?> <?xml-stylesheet type="text/xsl" href="sci_arztbrief.xsl"?> <levelone xmlns="urn::hl7-org/cda" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:sciphox="urn::sciphox-org/sciphox" xsi:schemaLocation="urn::hl7-org/cda sciphox-cda.xsd"> <clinical_document_header> <id RT="#cdh.docid.rt" EX="#cdh.docid.ex"/> <set_id RT="#cdh.docsetid.rt" EX="#cdh.docsetid.ex"/> <version_nbr V="#cdh.docvers"/> <document_type_cd V="#cdh.doctype.code" S="2.16.840.1.113883.6.1" DN="#cdh.doctype.name"/> <service_tmr V="#cdh.servtmr"/> <origination_dttm V="#cdh.origdttm"/> <confidentiality_cd V="#cdh.conf.code" S="2.16.840.1.113883.5.10228" DN="#cdh.conf.name" medidel="1"/> <!-- About 114 Lines with many nodes and childnodes deleted here to shorten the mail --> <intended_receipent> ------------SNIP-TEMPLATE-------------- ------------SNIP-OUTPUT-------------- <levelone xmlns="urn::hl7-org/cda" xmlns:sciphox="urn::sciphox-org/sciphox" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="urn::hl7-org/cda sciphox-cda.xsd"> <clinical_document_header> <id EX="179" RT="text-id"/> <version_nbr V="1"/> <document_type_cd DN="Befund" S="2.16.840.1.113883.6.1" V="11542-8"/> <intended_receipent> ------------SNIP-OUTPUT-------------- You see, between id and version_nbr is only one line blank and if you look in the template there is only on element node in between (the set_id element). Consecutive lines (no removed nodes) from the template are consecutive in the output too. If there are many nodes removed, this results in many blank lines. Please look at my code snipptes as follows: ------------SNIP--------CODE------------ void walk_tree() { DOMNode *nd; DOMImplementation *impl; DOMDocument *doc; // ... Code for initializing, getting the DOMNodeIterator a.s.o. stripped dom_RemoveNode(nd); // ... Blah blah blah do more other stuff (not with the DOMTree) dom_WriteDoc(impl, doc, "./myoutput.xml"); } void dom_RemoveNode(DOMNode *nd) { nd->getParentNode()->removeChild(nd); nd->release(); } void dom_WriteDoc(DOMImplementation* impl, DOMDocument *doc, char *filename) { DOMWriter* domwrite; XMLFormatTarget* formtarget; domwrite = ((DOMImplementationLS *) impl)->createDOMWriter(); domwrite->setFeature(X("format-pretty-print"), true); domwrite->setFeature(X("whitespace-in-element-content"), true); formtarget = new LocalFileFormatTarget(filename); domwrite->writeNode(formtarget, *doc); // Aufraeumen domwrite->release(); delete formtarget; } ------------SNIP--------CODE------------ I tried it without setting the "whitespace-in-element-content" too with no other effect. But i think it won't hurt anyway, as it belongs to "in-node-content" and not to "outside-of-node-characters", did it? I know, that my datafile is still a wellformed and maybe a valid document (or am i wrong here?), but it wastes space and makes it harder to read for humans in debugging purposes when it is watched with a normal texteditor. Please, can s.o. direct me in the right direction what to do to avoid this unwanted blank lines? Do i sth. wrong with my "removeChild" usage? Thx. in advance for your reply, help and for the time you willing to waste for my problems.
