// Use the PHP DOM-XML to create and parse XML files



// Create an XML document object. Subsequent processing will be performed on this basis.

// Subnode

// Set attributes for the subnode

Release of libxml either as a source archive or

RPM package from http://www.xmlsoft.org.

// Assign a value to it separately

(If you just use -- with-dom it ULTS

To/usr), I needed to use -- with-dom =/usr/local ");
