domxml_xmltree

Creates a tree of PHP objects from an XML document (PHP 4 >= 4.2.0)
DomDocument domxml_xmltree ( string str )

The function parses the XML document in str and returns a tree PHP objects as the parsed document.

This function is isolated from the other functions, which means you cannot access the tree with any of the other functions. Modifying it, for example by adding nodes, makes no sense since there is currently no way to dump it as an XML file.

However this function may be valuable if you want to read a file and investigate the content.

Parameters

str: The contents of the XML file.

Return Values

Returns a tree of Dom objects starting by a DomDocument.

You can modify the returned DomDocument, and dump it as an XML file by using DomDocument->dump_mem() or DomDocument->dump_file().

This is a genuinely useful function, however, as with any DOM-based markup parser, be mindful of the size of the XML document you are parsing. Representing very large XML files as object structures requires *a lot* of memory and processing, and may even crash your server (which is what happened to my Apache when I tried parsing a 2MB XML file using this function, just for fun... ;).

nutbar

Same concept as previous function, except uses node names as key items in the arrays. This function may prove a bit more useful than the previous one: function domxml_xmlarray($branch) { $object = array(); $objptr = &$object; $branch = $branch->first_child(); while ($branch) { if (!($branch->is_blank_node())) { switch ($branch->node_type()) { case XML_TEXT_NODE: { $objptr['cdata'] = $branch->node_value(); break; } case XML_ELEMENT_NODE: { $objptr = &$object[$branch->node_name()][]; break; } } if ($branch->has_child_nodes()) { $objptr = array_merge($objptr, domxml_xmlarray($branch)); } } $branch = $branch->next_sibling(); } return $object; } Usage is identical to the previous function.

Replacing line 10 works well, but replacing line 15 causes some errors. I have a tree like: <admin> <user level="0"> <username>admin</username> <password>admin_pass</password> </user> <user level="1"> <username>moder</username> <password>moder_pass</password> </user> </admin> when I remove those brackets only the last <user> is included into array. In this example it would be <user level="1"> <username>moder</username> <password>juozux</password> </user> no user name admin, etc. p.s. I don't store passwords in plain text in xml, that was just an example :))

In the function of nutbar, try to replace line 10 by $objptr = $branch->node_value(); and line 15 by : $objptr = &$object[$branch->node_name()]; //without the '[]' it makes an array much more easier to read. Previously, it produces an array like $MyArray[ROOT][0][BRANCH1][0][BRANCH2][0][5], and now $MyArray[ROOT][BRANCH1][BRANCH2][5]. There isn't bugs in the example I use, and I haven't tested with arguments. I think that an implementation of a part of nospam's code is enough. I hope this will help!

Forgive me if I am mistaken, but the whole point of including the "useless white space" is because of the existence of mixed types, for example: the schema def: <xsd:element name="paragraph"> <xsd:complexType mixed="true"> <xsd:choice> <xsd:element ref="link" /> <xsd:element ref="emphasisText" /> </xsd:choice> </xsd:complexType> </xsd:element> and an example: <paragraph>This here is a paragraph. You'll notice that it has within it a bunch of text punctuated by other <emphasisText>tags</emphasisText> and it is <link target="me.html>my</url> understanding that the only way to read this text is by reading the tagless nodes that your functions strip.</paragraph> I could be way off though...

Consider the following revisions for including attributes into the array. function domxml_xmlarray ($branch) { $object = Array (); $objptr =& $object; $branch = $branch->first_child (); while ($branch) { if (!($branch->is_blank_node())) { switch ($branch->node_type()) { case XML_TEXT_NODE: { $objptr['cdata'] = $branch->node_value (); break; } case XML_ELEMENT_NODE: { $objptr =& $object[$branch->node_name ()][]; if ($branch->has_attributes ()) { $attributes = $branch->attributes (); if (!is_array ($attributes)) { break; } foreach ($attributes as $index => $domobj) { $objptr[$index] = $objptr[$domobj->name] = $domobj->value; } } break; } } if ($branch->has_child_nodes ()) { $objptr = array_merge ($objptr, domxml_xmlarray ($branch)); } } $branch = $branch->next_sibling (); } return $object; }
