DomNode->get_content — Gets content of node
This function returns the content of the actual node.
Beispiel #1 Getting a content
<?php
if (!$dom = domxml_open_mem($xmlstr)) {
echo "Error while parsing the document\n";
exit;
}
$root = $dom->document_element();
$node_array = $root->get_elements_by_tagname("element");
for ($i = 0; $i<count($node_array); $i++) {
$node = $node_array[$i];
echo "The element[$i] is: " . $node->get_content();
}
?>
To print the node simply create a new document import the node and save it to html or whatever you need
e.g.:
<?php
$temp = new DOMDocument('1.0', 'UTF-8');
$temp_node = $temp->importNode($mynode, TRUE);
$temp->appendChild($temp_node);
$temp->saveHTML();
?>
Only to correct a very small error, but maybe difficult to find in che function GetContentAsString posted by someone in April 2005.
There was $anode-node_value() instead of $anode->node_value().
This is the right version:
<?php
function GetContentAsString($node) {
$st = "";
foreach ($node->child_nodes() as $cnode)
if ($cnode->node_type()==XML_TEXT_NODE)
$st .= $cnode->node_value();
else if ($cnode->node_type()==XML_ELEMENT_NODE) {
$st .= "<" . $cnode->node_name();
if ($attribnodes=$cnode->attributes()) {
$st .= " ";
foreach ($attribnodes as $anode)
$st .= $anode->node_name() . "='" .
$anode->node_value() . "'";
}
$nodeText = GetContentAsString($cnode);
if (empty($nodeText) && !$attribnodes)
$st .= " />"; // unary
else
$st .= ">" . $nodeText . "</" .
$cnode->node_name() . ">";
}
return $st;
}
?>
get_content() always returns UTF-8 (as should be!).
To get the content right just code it like
$myContent = utf8_decode($myNode->get_content());
Works fine!
Seems that get_content() always returns utf-8.
Opening document with something like
$dom->dump_mem(true,"ISO-8859-1")
makes no difference!
Here's a routine I wrote that acts like get_content() but returns embedded XHTML in the string returned. I needed this as I was wanting to embed HTML formatting codes in my HTML (e.g., "<br />") and converting them to HTML entities or using CDATA was a huge hassle.
<?php
function GetContentAsString($node) {
$st = "";
foreach ($node->child_nodes() as $cnode)
if ($cnode->node_type()==XML_TEXT_NODE)
$st .= $cnode->node_value();
else if ($cnode->node_type()==XML_ELEMENT_NODE) {
$st .= "<" . $cnode->node_name();
if ($attribnodes=$cnode->attributes()) {
$st .= " ";
foreach ($attribnodes as $anode)
$st .= $anode->node_name() . "='" .
$anode-node_value() . "'";
}
$nodeText = GetContentAsString($cnode);
if (empty($nodeText) && !$attribnodes)
$st .= " />"; // unary
else
$st .= ">" . $nodeText . "</" .
$cnode->node_name() . ">";
}
return $st;
}
?>
