There Was An Error With The Xpath Selector Unregistered Function

Regarding how to do what you want in XPath 1.0, it's not entirely clear what you'd like to do. etree.SubElement(results2, 'result').text = "Gamma" ... I haven't followed the code exactly yet, but it looks like nothing is ever moving incremented_opts into opts. asked 2 years ago viewed 684 times active 2 years ago Related 4Problem with namespace and libxml when i use Xpath5How can I access attributes and elements from XML::LibXML in Perl?2Why

Hoo, boy, would I feel stupid if that were the case! The empty prefix is therefore undefined for XPath and cannot be used in namespace prefix mappings. I may just have copied the wrong thing into the email, but I'll check. def execute(self, context, self_node, input_node, output_parent): ... you could check here

This includes numbers, boolean values, elements and lists of elements. In Saxon: In Xalan: >> def hello(context, a): ...

The error message was reporting an error in line 14. The document may define whatever prefixes it likes, including the empty prefix, without breaking the above code.

The xpath() method For ElementTree, the xpath method performs a global XPath query against the document (if absolute) or against the root node (if relative): >>> f = StringIO('') >>> tree I'm new to xpath so let me know if my syntax is incorrect, otherwise is there a chance the remove function can be supported? There are also specialized XPath evaluator classes that are more efficient for frequent evaluation: XPath and XPathEvaluator. In 1.0 you only have a few core functions - there's starts-with but not ends-with, no regular expression support, no date handling, etc.

How to measure Cycles per Byte of an Algorithm? Was there an error message? I'm doing the following program in C++: xsltStylesheetPtr XMLStyleSheetPtr = NULL; XMLStyleSheetPtr = xsltParseStylesheetFile((const xmlChar *)xsltFileName); exsltRegisterAll(); xmlDocPtr XMLDocumentPtr = xsltApplyStylesheet (XMLStyleSheetPtr, XMLDocumentPtr, NULL); This will apply the given stylesheet to

Some things are much easier to express in XSLT than in Python, while for others it is the complete opposite.

XSLT result objects The result of an XSL transformation can be accessed like a normal ElementTree document: >>> root = etree.XML('Text') >>> result = transform(root) >>> result.getroot().text 'Text' but, as opposed Note that http://localhost/xdv/Home -> http://www.seas.harvard.edu/administration/computing-it/Home and gives a 404 not found, so I just dropped the /Home from my test.

This is done using the FunctionNamespace class. It looks like the replace function was added in 1.1.20 (released Jan 2007). ``xsltproc --dumpextensions`` should list {http://exslt.org/strings}replace Laurence On 7 July 2010 16:16, Lars Kellogg-Stedman wrote: > The XSL Copying the master source list "sources.xml" into the correspondent directory in the POL virtual drive (in my case it's Office2010/drive_c/users/ps/Application Data/Microsoft/Bibliography) doesn't change anything - no sources are shown in the If you always use the same prefix for a function namespace, you can also register it with the namespace: >>> ns = etree.FunctionNamespace('http://mydomain.org/myother/functions') >>> ns.prefix = 'es' >>> ns['hello'] = ola

If you want a Python unicode string instead, you should set this encoding to UTF-8 (unless the ASCII default is sufficient).
