We use Acalog at our institution and want to use their (unsupported) API to pull catalog content into our site from theirs. I can access their files and pull out the information, but the formatting (paragraph, bold, italics, breaks) is done as nodes (h
, h:b, h:i, h:br). Unfortunately, the text I've pulled from searching for a:content only brings straight text and does not include the formatting nodes. How can I bring the nodes with the text? Where am I going wrong?The start of the XML (I broke it off at about the half mark)\[code\]<catalog xmlns="http://acalog.com/catalog/1.0" xmlns:h="http://www.w3.org/1999/xhtml" xmlns:a="http://www.w3.org/2005/Atom" xmlns:xi="http://www.w3.org/2001/XInclude" id="acalog-catalog-6"><hierarchy> <legend> <key id="acalog-entity-type-5"> <name>Department</name> <localname>Department</localname> </key> </legend> <entity id="acalog-entity-239"> <type xmlns:xi="http://www.w3.org/2001/XInclude"> <xi:include xmlns:xi="http://www.w3.org/2001/XInclude" xi:xpointer="xmlns(c=http://acalog.com/catalog/1.0) xpointer((//c:key[@id='acalog-entity-type-5'])[1])"/> </type> <a:title xmlns:a="http://www.w3.org/2005/Atom">American Studies</a:title> <code/> <a:content xmlns:a="http://www.w3.org/2005/Atom" xmlns:h="http://www.w3.org/1999/xhtml"> <h xmlns:h="http://www.w3.org/1999/xhtml"> <h:span class="dept_intro"> <h:i>Chair of the Department of American Studies: </h:i> </h:span> <h:span class="dept_intro">John Smith</h:span> <h:br/> <h:span class="dept_intro"> <h:br/>
