Two different issues here    Set the formatOutput and preserveWhiteSpace attributes to TRUE to generate formatted XML    doc- gt formatOutput   TRUE   doc- gt preserveWhiteSpace   TRUE   Many web browsers  namely Internet Explorer and Firefox  format XML when they display it  Use either the View Source feature or a regular text editor to inspect the output      See also xmlEncoding and encoding

Tried all the answers but none worked  Maybe it s because I m appending and removing childs before saving the XML  After a lot of googling found this comment in the php documentation  I only had to reload the resulting XML to make it work    outXML    xml- gt saveXML      xml   new DOMDocument      xml- gt preserveWhiteSpace   false    xml- gt formatOutput   true    xml- gt loadXML  outXML     outXML    xml- gt saveXML

You can try to do this          get completed xml document  doc- gt preserveWhiteSpace   false   doc- gt formatOutput   true   xml string    doc- gt 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- gt preserveWhiteSpace   false   doc- gt formatOutput   true    That s probably more concise  Output in both cases is  Demo     lt  xml version  1 0   gt   lt root gt     lt error gt       lt a gt eee lt  a gt       lt b gt sd lt  b gt       lt c gt df lt  c gt     lt  error gt     lt error gt       lt a gt eee lt  a gt       lt b gt sd lt  b gt       lt c gt df lt  c gt     lt  error gt     lt error gt       lt a gt eee lt  a gt       lt b gt sd lt  b gt       lt c gt df lt  c gt     lt  error gt   lt  root gt    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   gt  1   indent    gt  1   wrap    gt  0

This is a slight variation of the above theme but I m putting here in case others hit this and cannot make sense of it    as I did   When using saveXML    preserveWhiteSpace in the target DOMdocument does not apply to imported nodes  as at PHP 5 6     Consider the following code    dom   new DOMDocument                                    create a document  dom- gt preserveWhiteSpace   false                          disable whitespace preservation  dom- gt formatOutput   true                                 pretty print output  documentElement    dom- gt createElement  Entry             create a node  dom- gt appendChild   documentElement                       append it   message   new DOMDocument                                create another document  message- gt loadXML  messageXMLtext                         populate the new document from XML text  node  dom- gt importNode  message- gt documentElement true     import the new document content to a new node in the original document  documentElement- gt appendChild  node                       append the new node to the document Element  dom- gt saveXML  dom- gt documentElement                       print the original document   In this context   the  dom- gt saveXML    statement will NOT pretty print the content imported from  message  but content originally in  dom will be pretty printed   In order to achieve pretty printing for the entire  dom document  the line    message- gt preserveWhiteSpace   false     must be included after the  message   new DOMDocument    line - ie  the document s from which the nodes are imported must also have preserveWhiteSpace   false

With a SimpleXml object  you can simply   domxml   new DOMDocument  1 0     domxml- gt preserveWhiteSpace   false   domxml- gt formatOutput   true      var  xml SimpleXMLElement     domxml- gt loadXML  xml- gt asXML      domxml- gt save  newfile      xml is your simplexml object  So then you simpleXml can be saved as a new file specified by  newfile
