php - How to keep DOMNode::cloneNode() from inserting redundant namespaces? -


i'm using php's built-in dom implementation modify xml document, content.xml file in ods spreadsheet. document makes heavy use of namespaces (35 different namespaces declared in root element).

i'm trying copy table-cell element new row using shallow clonenode(), result not identical original:

<?xml version="1.0" encoding="utf-8"?> <office:document-content     xmlns:table="urn:oasis:names:tc:opendocument:xmlns:table:1.0"     xmlns:office="urn:oasis:names:tc:opendocument:xmlns:office:1.0"     xmlns:calcext="urn:org:documentfoundation:names:experimental:calc:xmlns:calcext:1.0"     [... snip 32 ...]>  <!-- original --> <table:table-cell table:style-name="ce5"                   office:value-type="string"                   calcext:value-type="string">  <!-- cloned --> <table:table-cell xmlns:table="urn:oasis:names:tc:opendocument:xmlns:table:1.0"                   xmlns:office="urn:oasis:names:tc:opendocument:xmlns:office:1.0"                   xmlns:calcext="urn:org:documentfoundation:names:experimental:calc:xmlns:calcext:1.0"                   table:style-name="ce5"                   office:value-type="string"                   calcext:value-type="string">

while semantically similar, can cause major bloat in larger spreadsheets (even though xml zipped on disk).

is there solution this?

the naive approach of using non-namespace aware methods, , copying attributes (including prefix , tag name), appears works, @ first:

$clone = $doc->createelement($ele->tagname); foreach ($ele->attributes $att) {     $clone->setattribute($att->nodename, $att->value); }

the resulting xml looks intended. when cloned element manipulated again:

$clone->setattributens($officens, "office:value-type", "string");

the result has two identical attribute names:

<table:table-cell xmlns:office="urn:oasis:names:tc:opendocument:xmlns:office:1.0"                   table:style-name="ce5"                   office:value-type="string"                   calcext:value-type="string"                   office:value-type="string"                   office:string-value="">

which makes document invalid. in general, found unpracticable mix namespaced , non-namespaced method calls.

here libxml constant allows optimize namespaces on loading:

$xml = <<<'xml' <f:foo xmlns:f="urn:foo">   <f:foo>     <f:foo xmlns:f="urn:foo">     </f:foo>   </f:foo> </f:foo> xml;  $document = new domdocument(); $document->loadxml($xml, libxml_nsclean); echo $document->savexml();

output:

<?xml version="1.0"?> <f:foo xmlns:f="urn:foo">   <f:foo>     <f:foo>     </f:foo>   </f:foo> </f:foo>

this works mostly, got invalid results if same prefix used different namespaces in same document.

the fluentdom library contains optimizer job. allows change/define prefixes, too.
