Dynamic parsing of xml with xslt

[chungtian]

I would like some help parsing a dynamic (folder.subfolders) xml with xslt, I tried a few things but I'm not there yet. Here is the structure of the xml that I have:\[code\]<FOLDERS> <FOLDER> <FOLDERID>2edfb864-5693-4e7f-8f98-4ef6e032d8a5</FOLDERID> <NAME>bla</NAME> <FOLDERSIZE>33Kb</FOLDERSIZE> <LASTMODIFIED>2012-06-07 11:11:02</LASTMODIFIED> <SUBFOLDERS /> <FILES> <FILE> <FILEID>1825</FILEID> <NAME>IMG_15052012_142711.png</NAME> <SIZE>33Kb</SIZE> <EXTENSION>png</EXTENSION> <LASTMODIFIED /> </FILE> </FILES> </FOLDER> <FOLDER> <FOLDERID>c9c5e2b2-ee93-49a2-b8be-d86e41528071</FOLDERID> <NAME>TestFolder</NAME> <FOLDERSIZE>0Kb</FOLDERSIZE> <LASTMODIFIED>2012-06-05 00:00:00</LASTMODIFIED> <SUBFOLDERS> <FOLDER> <FOLDERID>3b43fe58-db85-43e6-b541-77ce250afc78</FOLDERID> <NAME>SubFolder</NAME> <FOLDERSIZE>362Kb</FOLDERSIZE> <LASTMODIFIED>2012-06-05 00:00:00</LASTMODIFIED> <SUBFOLDERS> <FOLDER> <FOLDERID>ac1d35d0-80fd-4d97-8101-4de408f24dbd</FOLDERID> <NAME>subsub</NAME> <FOLDERSIZE>0Kb</FOLDERSIZE> <LASTMODIFIED>2012-06-05 00:00:00</LASTMODIFIED> <SUBFOLDERS /> <FILES /> </FOLDER> <FOLDER> <FOLDERID>7cfdc199-9d0e-4f86-904d-eda3521f3e87</FOLDERID> <NAME>SUBSUB1</NAME> <FOLDERSIZE>0Kb</FOLDERSIZE> <LASTMODIFIED>2012-06-05 00:00:00</LASTMODIFIED> <SUBFOLDERS /> <FILES /> </FOLDER> </SUBFOLDERS> <FILES> <FILE> <FILEID>1833</FILEID> <NAME>Untitled.png</NAME> <SIZE>121Kb</SIZE> <EXTENSION>png</EXTENSION> <LASTMODIFIED /> </FILE> <FILE> <FILEID>1834</FILEID> <NAME>Untitled.png</NAME> <SIZE>121Kb</SIZE> <EXTENSION>png</EXTENSION> <LASTMODIFIED /> </FILE> <FILE> <FILEID>1839</FILEID> <NAME>Untitled.png</NAME> <SIZE>121Kb</SIZE> <EXTENSION>png</EXTENSION> <LASTMODIFIED /> </FILE> </FILES> </FOLDER> </SUBFOLDERS> <FILES /> </FOLDER> <FOLDER> <FOLDERID>1ead58e2-a412-4318-9629-d5c70d8681bc</FOLDERID> <NAME>TestFolder1</NAME> <FOLDERSIZE>241Kb</FOLDERSIZE> <LASTMODIFIED>2012-06-05 00:00:00</LASTMODIFIED> <SUBFOLDERS /> <FILES> <FILE> <FILEID>1832</FILEID> <NAME>Untitled.png</NAME> <SIZE>121Kb</SIZE> <EXTENSION>png</EXTENSION> <LASTMODIFIED /> </FILE> <FILE> <FILEID>1837</FILEID> <NAME>Untitled.png</NAME> <SIZE>121Kb</SIZE> <EXTENSION>png</EXTENSION> <LASTMODIFIED /> </FILE> </FILES> </FOLDER> </FOLDERS> <FILES> <FILE> <FILEID>1836</FILEID> <NAME>Untitled.png</NAME> <SIZE>121Kb</SIZE> <EXTENSION>png</EXTENSION> <LASTMODIFIED /> </FILE> <FILE> <FILEID>1869</FILEID> <NAME>WallPaper.png</NAME> <SIZE>7.1Mb</SIZE> <EXTENSION>png</EXTENSION> <LASTMODIFIED /> </FILE> </FILES>\[/code\]The thing is that I don't know how deep the folders/subfolders tree can be.I did already something but it is still static, it needs to be dynamic also, especially the select part if the xslt condition.What do you guys think the best approach to parse the xml in this case?This is the structure I would like to have:\[code\]Folders Subfolders Subfolders Subfolders Files Files Files Files \[/code\]And this is what I have now:\[code\]<xsl:variable name="folderRoot" select="$xml/ROOT/FOLDERS/FOLDER" /><xsl:variable name="fileRoot" select="$xml/ROOT/FILES/FILE" />//Loop through the root folder<xsl:if test="count($folderRoot) > 0"> <xsl:call-template name="folder"/></xsl:if>//Loop through the root files <xsl:if test="count($fileRoot) > 0"> <xsl:call-template name="files"/></xsl:if>//files template <xsl:template name="files"> <xsl:for-each select="$fileRoot"> <tr> <td class="defaultIcon {EXTENSION}"> </td> <td> <xsl:value-of select="NAME" /> </td> </tr> </xsl:for-each> </xsl:template>//Folder template <xsl:template name="folder"> <xsl:for-each select="$folderRoot"> <tr> <td> <img src="http://stackoverflow.com/default/components/bestandsbeheer/images/folder.png" width="16" height="16" /> </td> <td> <xsl:value-of select="NAME"/> </td> <td> </td> <td>Map</td> <td> <xsl:value-of select="LASTMODIFIED" /> </td> </tr> <!--SUBFOLDER 1 --> <xsl:if test="count(SUBFOLDERS/FOLDER) > 0"> <xsl:for-each select="SUBFOLDERS/FOLDER"> <!--SUBFOLDER 2 --> <xsl:if test="count($folderRoot/SUBFOLDERS/FOLDER/SUBFOLDERS/FOLDER) > 0"> <xsl:for-each select="$folderRoot/SUBFOLDERS/FOLDER/SUBFOLDERS/FOLDER"> </xsl:for-each> </xsl:if> <xsl:if test="count($folderRoot/SUBFOLDERS/FOLDER/FILES) > 0"> <xsl:for-each select="$folderRoot/SUBFOLDERS/FOLDER/FILES"> </xsl:for-each> </xsl:if> </xsl:for-each> </xsl:if> //Files belong to a sub folder <xsl:if test="count(FILES) > 0"> <xsl:for-each select="FILES/FILE"> </xsl:for-each> </xsl:if> </xsl:for-each> </xsl:template>\[/code\]Let me know if something is not clear.
