PHP XML how to output nice format
domdocument, php, xml
Solution
You can try to do this:
...
// get completed xml document
$doc->preserveWhiteSpace = false;
$doc->formatOutput = true;
$xml_string = $doc->saveXML();
echo $xml_string;
You can make set these parameter right after you've created the `DOMDocument` as well:
$doc = new DomDocument('1.0');
$doc->preserveWhiteSpace = false;
$doc->formatOutput = true;
That's probably more concise. Output in both cases is (Demo):
<?xml version="1.0"?>
<root>
<error>
<a>eee</a>
<b>sd</b>
<c>df</c>
</error>
<error>
<a>eee</a>
<b>sd</b>
<c>df</c>
</error>
<error>
<a>eee</a>
<b>sd</b>
<c>df</c>
</error>
</root>
I'm not aware how to change the indentation character(s) with `DOMDocument`. You could post-process the XML with a line-by-line regular-expression based replacing (e.g. with `preg_replace`):
$xml_string = preg_replace('/(?:^|\G) /um', "\t", $xml_string);
Alternatively, there is the tidy extension with `tidy_repair_string` which can pretty print XML data as well. It's possible to specify indentation levels with it, however tidy will never output tabs.
tidy_repair_string($xml_string, ['input-xml'=> 1, 'indent' => 1, 'wrap' => 0]);
Problem
Here are the codes: ``` $doc = new DomDocument('1.0'); // create root node $root = $doc->createElement('root'); $root = $doc->appendChild($root); $signed_values = array('a' => 'eee', 'b' => 'sd', 'c' => 'df'); // process one row at a time foreach ($signed_values as $key => $val) { // add node for each row $occ = $doc->createElement('error'); $occ = $root->appendChild($occ); // add a child node for each field foreach ($signed_values as $fieldname => $fieldvalue) { $child = $doc->createElement($fieldname); $child = $occ->appendChild($child); $value = $doc->createTextNode($fieldvalue); $value = $child->appendChild($value); } } // get completed xml document $xml_string = $doc->saveXML() ; echo $xml_string; ``` If I print it in the browser I don't get nice XML structure like ``` <xml> \n tab <child> etc. ``` I just get ``` <xml><child>ee</child></xml> ``` And I want to be utf-8 How is this all possible to do?
