| Search and replace multiple file Hi Pythonist, I write the code in Python for search and replace the text in all XML files at current directory. But I'm unable to find and replace the text "<tex>" as empty in all XML files. Here I want to remove the text: <tex>z_{1 - \alpha }^2 \,\sigma _{{\rm SCR}}^2 = \sum\limits_{i = 1}^n {z_{1 - \alpha }^2 \,\sigma _i^2 } + 2\sum\limits_{i \ne }^n {\sum\limits_j^n {z_{1 - \alpha }^2 \,\rho _{ij} \,\sigma _i \,\sigma _j } } ,</tex> as empty ie. re.sub(r"<tex>(.*)</tex>",r"", filePath) whats wrong with this code and explain how and where to use the script. And also I want to replace all starting with <mtml> as <mml:mathml> and <m...> as <mml:m...> within the element <fd id="1" cnt="1"><no>1a</no> for all XML files in the current directory. Here I want to replace the text: risk modules:<fd id="1" cnt="1"><no>1a</no><mtml><mrow><msubsup><mi><mi>z</mi></mi><mrow><mn>1</mn><mo>-</mo><mi><mi>α</mi></mi></mrow><mn>2</mn></msubsup><mi> </mi><msubsup><mi><mi>σ</mi></mi><mrow><mtext>SCR</mtext></mrow><mn>2</mn></msubsup><mo>=</mo><munderover><mo>∑</mo><mrow><mi><mi>i</mi></mi><mo>=</mo><mn>1</mn></mrow><mi><mi>n</mi></mi></munderover><mrow><msubsup><mi><mi>z</mi></mi><mrow><mn>1</mn><mo>-</mo><mi><mi>α</mi></mi></mrow><mn>2</mn></msubsup><mi> </mi><msubsup><mi><mi>σ</mi></mi><mi><mi>i</mi></mi><mn>2</mn></msubsup></mrow><mo>+</mo><mn>2</mn><munderover><mo>∑</mo><mrow><mi><mi>i</mi></mi><mo>≠</mo></mrow><mi><mi>n</mi></mi></munderover><mrow><munderover><mo>∑</mo><mi><mi>j</mi></mi><mi><mi>n</mi></mi></munderover><mrow><msubsup><mi><mi>z</mi></mi><mrow><mn>1</mn><mo>-</mo><mi><mi>α</mi></mi></mrow><mn>2</mn></msubsup><mi> </mi><msub><mi><mi>ρ</mi></mi><mrow><mi><mi>i</mi><mi>j</mi></mi></mrow></msub><mi> </mi><msub><mi><mi>σ</mi></mi><mi><mi>i</mi></mi></msub><mi> </mi><msub><mi><mi>σ</mi></mi><mi><mi>j</mi></mi></msub></mrow></mrow><mtext><mo>,</mo></mtext></mrow></mtml><tex>z_{1 - \alpha }^2 \,\sigma _{{\rm SCR}}^2 = \sum\limits_{i = 1}^n {z_{1 - \alpha }^2 \,\sigma _i^2 } + 2\sum\limits_{i \ne }^n {\sum\limits_j^n {z_{1 - \alpha }^2 \,\rho _{ij} \,\sigma _i \,\sigma _j } } ,</tex></fd>where as risk modules:<fd id="1" cnt="1"><no>1a</no><mml:mathml><mml:row><mml:subsup><mml:i><mml:i>z</mml:i></mml:i><mml:row><mml:n>1</mml:n><mml:o>-</mml:o><mml:i><mml:i>α</mml:i></mml:i></mml:row><mml:n>2</mml:n></mml:subsup><mml:i> </mml:i><mml:subsup><mml:i><mml:i>σ</mml:i></mml:i><mml:row><mml:text>SCR</mml:text></mml:row><mml:n>2</mml:n></mml:subsup><mml:o>=</mml:o><mml:underover><mml:o>∑</mml:o><mml:row><mml:i><mml:i>i</mml:i></mml:i><mml:o>=</mml:o><mml:n>1</mml:n></mml:row><mml:i><mml:i>n</mml:i></mml:i></mml:underover><mml:row><mml:subsup><mml:i><mml:i>z</mml:i></mml:i><mml:row><mml:n>1</mml:n><mml:o>-</mml:o><mml:i><mml:i>α</mml:i></mml:i></mml:row><mml:n>2</mml:n></mml:subsup><mml:i> </mml:i><mml:subsup><mml:i><mml:i>σ</mml:i></mml:i><mml:i><mml:i>i</mml:i></mml:i><mml:n>2</mml:n></mml:subsup></mml:row><mml:o>+</mml:o><mml:n>2</mml:n><mml:underover><mml:o>∑</mml:o><mml:row><mml:i><mml:i>i</mml:i></mml:i><mml:o>≠</mml:o></mml:row><mml:i><mml:i>n</mml:i></mml:i></mml:underover><mml:row><mml:underover><mml:o>∑</mml:o><mml:i><mml:i>j</mml:i></mml:i><mml:i><mml:i>n</mml:i></mml:i></mml:underover><mml:row><mml:subsup><mml:i><mml:i>z</mml:i></mml:i><mml:row><mml:n>1</mml:n><mml:o>-</mml:o><mml:i><mml:i>α</mml:i></mml:i></mml:row><mml:n>2</mml:n></mml:subsup><mml:i> </mml:i><mml:sub><mml:i><mml:i>ρ</mml:i></mml:i><mml:row><mml:i><mml:i>i</mml:i><mml:i>j</mml:i></mml:i></mml:row></mml:sub><mml:i> </mml:i><mml:sub><mml:i><mml:i>σ</mml:i></mml:i><mml:i><mml:i>i</mml:i></mml:i></mml:sub><mml:i> </mml:i><mml:sub><mml:i><mml:i>σ</mml:i></mml:i><mml:i><mml:i>j</mml:i></mml:i></mml:sub></mml:row></mml:row><mml:text><mml:o>,</mml:o></mml:text></mml:row></mml:mathml> </fd>where Pls. explain how and where to use the script.

Thanks in advance Naren |
