updated wiki documentation for IgorPro? binding

File size: 8.4 KB
1= canSAS 1-D SAS XML format binding to IgorPro =
3An import tool (binding) for IgorPro has been created (cansasXML.ipf).
4You can check out the IgorPro working directory from the SVN server (see 
5[[#Checkout_of_support_code_in_Subversion | instructions below]]).
7To use the canSASxml.ipf procedure, you must have the XMLutils XOP
8IGOR plugin installed.  See the [[#Usage_Notes | Usage Notes]] below.
10Note that the code described here is ''not a complete user interface''.
11(See further comments [[#List_of_Functions | below]].)
12It is expected that this code will be called by a graphical user interface routine
13and that routine will handle the work of copying the loaded SAS data in
14IgorPro from the <nowiki>root:Packages:CS_XMLreader</nowiki> data folder to the destination
15of choice (including any renaming of waves as desired).

42=== Checkout of support code in Subversion ===
44Subversion ( is a program for
45managing software versions.  There are command line and GUI clients
46for a variety of operating systems.  We won't recommend any here
47but will show the command lines necessary.
49==== XMLutils XOP ====
51The XMLutils XOP, written by Andrew Nelson (ANSTO), is hosted
52on the IgorExchange (
54One good location to place the checked out XMLutils directory
55is in the Wavemetrics directory, next to the <nowiki>Igor Pro Folder</nowiki>
56<pre>svn:// XMLutils</pre>
58In the future, to retrieve an updated version of this support, go into
59the <nowiki>XMLutils</nowiki> directory (created above) and type the command
60<pre>svn update</pre>
61This will check the repository and update files as needed.
62If the installer program was updated, you;ll need to run the new
63installer program.  It is not necessary to uninstall first.
65The installer executables contained in the download will
66do all the installation for you.  They will place the XOP in the folder
67''/User Procedures/motofit/XMLutils'', and create a shortcut/alias to the
68plugin in /Igor Extensions.
69Packages from other facilities should place the XOP there as well.
71==== cansasXML.ipf ====
73Check out the canSAS 1d SAS XML reader from the subversion repository:
74<pre>svn checkout cansas-1dwg</pre>
76This will download lots of extra files.  The file of interest is in the <nowiki>IgorPro</nowiki>
77directory and is called <nowiki>cansasXML.ipf</nowiki>
79In the future, to retrieve an updated version of this support, go into
80the <nowiki>cansas-1dwg</nowiki> directory (created above) and type the command
81<pre>svn update</pre>
82This will check the repository and update files as needed.
84==  Installation  ==
86# License and Install IgorPro (should have already been done by now)
87# Quit IgorPro if it is running
88# Download XMLutils XOP.  Either checkout from subversion (see above) or, with a web browser, go to
89# Install XMLutils XOP by double-clicking the installer for you operating system.
90# Download cansasXML.ipf.  Either checkout from subversion (see above) or, with a web browser, copy cansasXML.ipf from on-line subversion repository:
91# Copy cansasXML.ipf file to <nowiki>...\Wavemetrics\Igor Pro Folder\User Procedures</nowiki> (or file system equivalent)
92# Then, you should be able to restart IgorPro and progress from there
94==  Usage Notes  ==
96To use the canSASxml.ipf procedure, you must have the XMLutils XOP
97IGOR plugin installed. This may be downloaded from the IgorExchange
98Project site. There are installer executables contained in the
99download that will do all the installation for you. Each installer will place
100the XOP in the folder
101<nowiki>...\Wavemetrics\Igor Pro Folder\User Procedures\motofit\XMLutils</nowiki>,
102and create
103a shortcut/alias to the plugin in
104<nowiki>...\Wavemetrics\Igor Pro Folder\Igor Extensions</nowiki>.
107==  List of Functions  ==
109These are (most of) the FUNCTIONS in the cansasXML.ipf code.
110The only functions of interest are '''CS_XmlReader(fileName)'''
111which reads the named XML file and and loads SAS data and the two demonstration
112functions '''prj_grabMyXmlData()''' and '''prjTest_cansas1d()'''
113that together show a usage example.
115;'''CS_XmlReader(fileName)''': open a canSAS 1-D reduced SAS XML data file
116*input: ''fileName'' (string) name of canSAS XML file (can include file system path name to file)
118**0 successful
119**-1: XML file not found
120**-2: root element is not <SASroot> with valid canSAS namespace
121**-3: <SASroot> version  is not 1.0
122**-4: no <SASentry> elements (NOT USED NOW)
123**-5: XOPutils needs upgrade
124;CS_1i_parseXml(fileID): '''This is what guides the work''', given a file ID returned from '''XMLOpenFile()''', parses that file for SAS data and metadata <br /> (1i in the function name signifies this is a function that supports INPUT from version 1.0 XML files)
125;CS_1i_getOneSASdata(fileID, Title, SASdataPath): harvest the data and metadata in the specific SASdata element
126;CS_1i_getOneVector(file,prefix,XML_name,Igor_name): harvest just one column (vector) of data
127;CS_1i_GetReducedSASdata(fileID, SASdataPath): grab the data and put it in the working data folder
128;CS_1i_locateTitle(fileID, SASentryPath): determine the title for this experiment
129;CS_appendMetaData(fileID, key, xpath, value): queries XML file for '''xpath'''.  If '''value''' is not empty, appends it to '''metadata''' where ''last'' is the new last row: <nowiki>metadata[last][0]=key; metadata[last][1]=value</nowiki>
130;CS_buildXpathStr(prefix, value): this function can be used only with very simple XPath constructions
131;CS_cleanFolderName(proposal): given a proposal string, returns a candidate folder name for immediate use
132;CS_findElementIndex(matchStr): looks for element index in structure ''W_ElementList'' returned from call to '''XmlElemList(fileID)'''
133;CS_getDefaultNamespace(fileID): returns the string containing the default namespace for the XML file
134;CS_registerNameSpaces(): Builds a table of all namespaces used in the XML file and appends '''W_ElementList''' with full namespace-xpath string for each element.
135;CS_simpleXmlListXpath(fileID, prefix, value): Calls '''XMLlistXpath()''' with proper namespace prefix attached.
136;CS_simpleXmlWaveFmXpath(fileID, prefix, value): Calls '''XMLwaveFmXpath()''' with proper namespace prefix attached.
137;CS_updateWaveNote(wavName, key, value): adds (or replaces) definition of ''key''=''value'' in the wave note of ''wavName''
138;CS_XmlStrFmXpath(fileID, prefix, value): Calls '''XmlStrFmXpath()''' with proper namespace prefix attached.  Trims the result string.
139;CS_XPath_NS(simpleStr): this function adds namespace info as necessary to simpleStr (an XPath)
140;TrimWS(str): Calls '''TrimWSL(TrimWSR(str))'''
141;TrimWSL(str): Trims white space from left (leading) end of '''str'''
142;TrimWSR(str): Trims white space from right (trailing) end of '''str'''
143;prjTest_cansas1d(): Demonstration function that calls '''CS_XmlReader(fileName)''' for many of the test data sets.
144;prj_grabMyXmlData(): Demonstration function that moves loaded data from <nowiki>root:Packages:CS_XMLreader</nowiki> to a user's data folder.  (In this ''example'', that folder is <nowiki>root:PRJ_canSAS</nowiki>.)
145;testCollette(): Demonstration function that reads an ISIS/LOQ file and copies the data to the root folder a la COLLETE
