    <p>I have Generated an XML with dom and i want to use lxml to pretty print the xml. </p> <p>this is my code for pretty print the xml </p> <pre><code>def prettify_xml(xml_str): import lxml.etree as etree root = etree.fromstring(xml_str) xml_str = etree.tostring(root, pretty_print=True) return xml_str </code></pre> <p>my output should be an xml formatted string.</p> <p>I got this code from some post in stactoverflow. This works flawlessly when i am compiling wit python itself. But when i convert my project to a binary created from py2exe (my binary is windows service with a namedpipe).I had two problems:</p> <ol> <li><p>My service was not starting , i solved this by adding <code>lxml.etree</code> in <code>includes</code> option in py2exe function. then on my service started properly. </p></li> <li><p>when xml generation in called here, is the error which I am seeing in my log <code>'module' object has no attribute 'fromstring'</code></p></li> </ol> <p>where do i rectify this error ? And Is my first problem's solution correct ?</p> <p>my xml generation Code : </p> <pre><code>from xml.etree import ElementTree from xml.dom import minidom from xml.etree.ElementTree import Element, SubElement, tostring, XML import lxml.etree def prettify_xml(xml_str): root = lxml.etree.fromstring(xml_str) xml_str = lxml.etree.tostring(root, pretty_print=True) return xml_str def dll_xml(status): try: xml_declaration = '&lt;?xml version="1.0" standalone="no" ?&gt;' rootTagName='response' root = Element(rootTagName) root.set('id' , 'rp001') parent = SubElement(root, 'command', opcode ='-ac') # Create children chdtag1Name = 'mode' chdtag1Value = 'repreport' chdtag2Name='status' chdtag2Value = status fullchildtag1 = ''+chdtag1Name+' value = "'+chdtag1Value+'"' fullchildtag2=''+chdtag2Name+' value="'+chdtag2Value+'"' children = XML('''&lt;root&gt;&lt;'''+fullchildtag1+''' /&gt;&lt;'''+fullchildtag2+'''/&gt;&lt;/root&gt; ''') # Add parent parent.extend(children) dll_xml_doc = xml_declaration + tostring(root) dll_xml_doc = prettify_xml(dll_xml_doc) return dll_xml_doc except Exception , error: log.error("xml_generation_failed : %s" % error) </code></pre>

    1. CODoes it still happen if you move the import outside of the method definition? And are you sure py2exe is using the same python version as the one you're testing in?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
