Overview
|
XMLStarlet is a set of command line utilities (tools) which can be used
to transform, query, validate, and edit XML documents and files using
simple set of shell commands in similar way it is done for plain text files
using UNIX grep, sed, awk, diff, patch, join, etc commands.
This set of command line utilities can be used by those who deal with many XML documents on UNIX shell
command prompt as well as for automated XML processing with shell scripts.
The toolkit's feature set includes options to:
- Check or validate XML files (simple well-formedness check, DTD, XSD, RelaxNG)
- Calculate values of XPath expressions on XML files (such as running sums, etc)
- Search XML files for matches to given XPath expressions
- Apply XSLT stylesheets to XML documents (including EXSLT support, and passing parameters to stylesheets)
- Query XML documents (ex. query for value of some elements of attributes, sorting, etc)
- Modify or edit XML documents (ex. delete some elements)
- Format or "beautify" XML documents (as changing indentation, etc)
- Fetch XML documents using http:// or ftp:// URLs
- Browse tree structure of XML documents (in similar way to 'ls' command for directories)
- Include one XML document into another using XInclude
- XML c14n canonicalization
- Escape/unescape special XML characters in input text
- Print directory as XML document
- Convert XML into PYX format (based on ESIS - ISO 8879), and vice versa
XMLStarlet command line utility is written in C and uses libxml2 and libxslt from http://xmlsoft.org/.
Implementation of extensive choice of options for XMLStarlet utility was only possible because of rich
feature set of libxml2 and libxslt (many thanks to the developers of those libraries for great work).
'diff' and 'patch' options are not currently implemented. Other features need some work too. Please, send an email
to the project administrator (see http://sourceforge.net/projects/xmlstar/) if you wish to help.
XMLStarlet is linked statically to both libxml2 and libxslt, so generally all you need to process XML documents is one executable file.
To run XmlStarlet utility you can simple type 'xml' on command line and see list of options available.
XMLStarlet is open source free software under MIT license which allows free use and distribution for both
commercial and non-commercial projects.
We welcome any user's feedback on this project which would greatly help us to improve its quality.
