#23531 [Opn->Bgs]: Can't reset internal treenode to correctly reread xml document

ID: 23531 Updated by: chregu@php.net Reported By: bharris at spro dot net -Status: Open +Status: Bogus Bug Type: DOM XML related Operating System: Red Hat 8.0 PHP Version: 4.3.2RC2 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The internal node pointer (I assume you mean the 0 and 1 properties) were never meant to be used in PHP Userland. Don't rely on them... That these pointers are exposed to the outside looks is a misconception in the domxml extension. chregu Previous Comments: ------------------------------------------------------------------------ [2003-05-07 13:02:03] bharris at spro dot net --SCRIPT-- $xmlstr = '<?xml version="1.0"?><configuration><datasources><subtree name="Test"><apply-template name="test.xml.com"/></subtree></datasources></configuration>'; $dom = domxml_open_mem($xmlstr); $root = $dom->document_element(); $element = 0; transversenodes($root, 'first'); $dom->free(); $dom = domxml_open_mem($xmlstr); $root = $dom->document_element(); $element = 0; transversenodes($root, 'second'); nice_r($_SESSION); function transversenodes (&$node, $string) { global $element; if ($node->has_child_nodes()) { $child = $node->child_nodes(); for ($i = 0; $i < count($child); $i++) { if ($child[$i]->node_type() == XML_ELEMENT_NODE) { if ($child[$i]->tagname == 'apply-template') { $_SESSION[$string][$element] = $child[$i]; $element++; break; } if ($child[$i]->tagname == 'subtree') { $_SESSION[$string][$element] = $child[$i]; $element++; } transversenodes($child[$i], $string); } } } } function nice_r (&$variable) { echo "<pre>\n"; print_r($variable); echo "</pre>\n"; } --MODULES-- './configure' '--host=i386-redhat-linux' '--build=i386-redhat-linux' '--target=i386-redhat-linux-gnu' '--program-prefix=' '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/bin' '--sbindir=/usr/sbin' '--sysconfdir=/etc' '--datadir=/usr/share' '--includedir=/usr/include' '--libdir=/usr/lib' '--libexecdir=/usr/libexec' '--localstatedir=/var' '--sharedstatedir=/usr/com' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--prefix=/usr' '--with-config-file-path=/etc' '--enable-force-cgi-redirect' '--disable-debug' '--enable-pic' '--disable-rpath' '--enable-inline-optimization' '--with-bz2' '--with-curl' '--with-dom=/usr' '--with-exec-dir=/usr/bin' '--with-freetype-dir=/usr' '--with-png-dir=/usr' '--with-gd' '--enable-gd-native-ttf' '--with-ttf' '--with-gdbm' '--with-gettext' '--with-ncurses' '--with-gmp' '--with-iconv' '--with-jpeg-dir=/usr' '--with-openssl' '--with-png' '--with-pspell' '--with-xml' '--with-expat-dir=/usr' '--with-zlib' '--with-layout=GNU' '--enable-bcmath' '--enable-exif' '--enable-ftp' '--enable-magic-quotes' '--enable-safe-mode' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-discard-path' '--enable-track-vars' '--enable-trans-sid' '--enable-yp' '--enable-wddx' '--without-oci8' '--with-pear=/usr/share/pear' '--with-imap=shared' '--with-imap-ssl' '--with-kerberos=/usr/kerberos' '--with-ldap=shared' '--with-mysql=shared,/usr' '--with-pgsql=shared' '--with-snmp=shared,/usr' '--with-snmp=shared' '--enable-ucd-snmp-hack' '--with-unixODBC=shared' '--enable-memory-limit' '--enable-bcmath' '--enable-shmop' '--enable-versioning' '--enable-calendar' '--enable-dbx' '--enable-dio' '--enable-mcal' '--with-apxs2=/usr/sbin/apxs' --COMMENTS-- I appologize for the length of the test script but I couldn't trim it any more to show my point My problem is that I can't reset the internal namespace for DOMXML documents unless I load a new page (i.e. can't reset the dom space within a single script). I need to have access to functions that will do whatever is done between page loads because that successfully resets the internal treenode pointer. I need to be able to load a document into an internal treenode, modify it, write it to file then display a graphical hyperlinked representation of the modified treenode on the same "page". Without being able to reset the internal treenode my serialized objects don't point at the correct object on the next page and I get an error. Reclicking the same hyperlink at this point works because ending the script the first time resets the internal treenode correctly. I thought $dom->free() would work but it appears it's not, if you run my script you'll see that the object id's are different for the second dom object even though it's the same document, just reloaded. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23531&edit=1
