NAME
xml_grep - grep XML files looking for specific elements
SYNOPSYS
xml_grep [options] <file list> or xml_grep <xpath expression> <file list> By default you can just give "xml_grep" an XPath expression and a list of files, and get an XML file with the result. This is equivalent to writing xml_grep --group_by_file file --pretty_print indented --cond <file list>
OPTIONS
--help brief help message --man full documentation --Version display the tool version --root <cond> look for and return xml chunks matching <cond> if neither "--root" nor "--file" are used then the element(s) that trigger the "--cond" option is (are) used. If "--cond" is not used then all elements matching the <cond> are returned several "--root" can be provided --cond <cond> return the chunks (or file names) only if they contain elements matching <cond> several "--cond" can be provided (in which case they are OR'ed) --files return only file names (do not generate an XML output) usage of this option precludes using any of the options that define the XML output: "--roots", "--encoding", "--wrap", "--group_by_file" or "--pretty_print" --count return only the number of matches in each file usage of this option precludes using any of the options that define the XML output: "--roots", "--encoding", "--wrap", "--group_by_file" or "--pretty_print" --strict without this option parsing errors are reported to STDOUT and the file skipped --date when on (by default) the wrapping element get a "date" attribute that gives the date the tool was run. with "--nodate" this attribute is not added, which can be useful if you need to compare 2 runs. --encoding <enc> encoding of the xml output (utf-8 by default) --nb_results <nb> output only <nb> results --by_file output only <nb> results by file --wrap <tag> wrap the xml result in the provided tag (defaults to 'xml_grep') If wrap is set to an empty string ("--wrap ''") then the xml result is not wrapped at all. --nowrap same as using "--wrap ''": the xml result is not wrapped. --descr <string> attributes of the wrap tag (defaults to "version="<VERSION>" date="<date>"") --group_by_file <optional_tag> wrap results for each files into a separate element. By default that element is named "file". It has an attribute named "filename" that gives the name of the file. the short version of this option is -g --exclude <condition> same as using "-v" in grep: the elements that match the condition are excluded from the result, the input file(s) is (are) otherwise unchanged the short form of this option is -v --pretty_print <optional_style> pretty print the output using XML::Twig styles ('"indented"', '"record"' or '"record_c"' are probably what you are looking for) if the option is used but no style is given then '"indented"' is used short form for this argument is -s --text_only Displays the text of the results, one by line. --html Allow HTML input, files are converted using HTML::TreeBuilder --Tidy Allow HTML input, files are converted using HTML::Tidy Condition Syntax <cond> is an XPath-like expression as allowed by XML::Twig to trigger handlers. exemples: 'para' 'para[@compact="compact"]' '*[@urgent]' '*[@urgent="1"]' 'para[string()="WARNING"]' see XML::Twig for a more complete description of the <cond> syntax options are processedby Getopt::Long so they can start with '-' or '--' and can be abbreviated ("-r" instead of "--root" for example)
DESCRIPTION
xml_grep does a grep on XML files. Instead of using regular expressions it uses XPath expressions (in fact the subset of XPath supported by XML::Twig) the results can be the names of the files or XML elements containing matching elements.
